Bleeding After Sex – When To Worry

naza-profile-photoBleeding after sex is no small matter.

This can easily affect you psychologically, having you worried after, or even during lovemaking.

Unless your periods are irregular or if you are 45 and above, infection is most likely the cause.

Infection often gives additional symptoms such as itchiness, bad odor and abnormal discharges, all of which may be noticed before one realizes any bleeding or pain (which may accompany) during sex.

Irregular Menses

If you are experiencing irregular menstruation, this might answer the question. You might not realize that your menses have coincided with your sexual intercourse and might seem like the bleeding is because of intercourse. Get your calendar and pay attention to the characteristics of the blood. Other than lower abdominal pain in the first few days of menses, no additional pain should be felt when this happens.


Being in your late 40s is a criteria for regular gynecological check-ups. Bleeding at this age, with or without intercourse, calls for a doctor’s visit to determine the source of bleeding. Cervical cancer is the number one suspect which should be ruled out during your visit. Endometrial Cancer is rarer but also a possible cause.

Abrasions and Injuries

Rough sex may also cause tears and lacerations of the vaginal walls. Should this happen, wash and apply antiseptic with alcohol or povidone immediately to prevent any infection. Strict hygiene should be practiced.

Friction may be experienced during intercourse when the vaginal walls are dry. This may cause bleeding and pain during sex. A decreased level of oestrogen in your body is a more common cause compared to severe dehydration; thus, women who are approaching menopause or after menopause might wish to apply lubricants prior to intercourse.

Sagging of the cervical/vaginal wall, also popularly known as a polyp, may bleed when slightly touched. Bleeding may be slightly profuse and may be accompanied by yellowish discharge at times. If bleeding doesn’t stop, vaginal packing (applying pressure on the vagina with a gauze) and immediate visit to a doctor is necessary.

Possible causes: – Infection – STDs – Cancers – Polyps – Abrasions – Others

What to do

When you are experiencing any kind of vaginal bleeding, it is best to abstain from sex for the time being until you see a doctor. This will get your bleeding controlled and allow you to monitor its characteristics – whether or not it happens after intercourse, its frequency, amount and its constancy. Besides, it will help prevent spreading of unknown underlying infection. If bleeding is profuse, as mentioned above, vaginal packing with mild pressure should be applied and immediately see a doctor.  Pain can be temporarily relieved by aspirin or diclofenac found at any pharmacy.

Be sure to practice a strict hygiene as any injury or abnormality of the vagina or cervix is a welcoming sign to infection. Washing after your visit to the toilet assures safety from gonorrheal or other bacterial infection. Be sure to consult Our Doctors before taking any over-the-counter antibiotics, as they may aggravate fungal infection if the fungus is the culprit. Watch out for other abnormalities and changes, such as pain, increased or continuous bleeding and any kind of discharge.

If the bleeding is continuous or stops then occurs again or is painful or you have a discharge, please see Our Doctors immediately.

  1. Hi i had unprotected sex 3 days ago and it was only real quick wasnt that long and afterwards i went to the bathroom and as i was peeing some small chunks of brown were coming out of my vagina…this has never happened before this is the first time it has, then next day i had protected sex and i asked for it harder (sorry so detailed) so he did and when he did we stopped cause my stomach started hurting i then went to the bathroom and i was bleeding like when i lost my virginity after a few hours it stopped then again that night we had sex again but not so rough…the next morning it look like maybe my wetness was coming out and there was very light bleeding with it…is something bad going on…what should i do??

    • Bleeding after sex could be completely benign like from a tear or abrasion or something more sinister like cancer or pre-cancer. In such situations we would always tell you to see your doctor. You really need to know exactly what is causing the bleeding.

  2. Hi Doc
    I have a new partner and we have sex on the last day of my period on the other day we have sex again and I got bleed and feels like teared down in my vagina. From heavy bleeding to light for the whole 24 days. No other pain just bleeding.

    • The bleeding is most likely from the tear. GO see your doctor if it does not clear up in a few days.

  3. Hello

    • I had a yeast infection earlier last year and tried a 3-day over the counter suppository (capsule) which didn’t help, so I tried a different one which also didn’t help. Then I tried a cream and that helped! However, the last 4 times that I had sex, I always bleed and it feels a little tender inside. My partner also stuck his finger in my rectum (sorry for the details) and when I used the bathroom I had bright red blood in my stool, and the tissue looked like I was menstruating.. From the wrong end… I know anal can sometimes cause bleeding but this seemed to be a lot.. Should I go to the ER? I also feel a little bloated almost asthough I have my period.

      • Bleeding after sex is always a little worrying. Although most of the time it is only due to benign causes such as polyps or abrasions, doctors will not feel totally comfortable until we have ruled out the big C – Cancers. Fresh bleeding from the rectum is less worrying. That is more likely just due to piles. You definitely should see your doctor to get checked.

  4. Hi doctor, I had my menstruation a week ago. Two days ago I had sexual intercourse with my partner and eventually I started experiencing dark bleeding. I took morning after pill before my last period. What is the cause? Will it be any chances of pregnancy ? I really need help. I am very grateful if you can give me a reply. Thank you so much.

    • So 5 days into your period you had sex then saw dark blood. Most likely it is remnant blood in the uterus that was pumped out during the intercourse.

  5. A 27 year old femaile patients would like to schedule an appointment due to some bright red bleeding after sexual intercourseWhat conditions or disease might be of concern for this woman? Discuss your reasoning behind choosing the conditions you did.

    What type of exam might the physician wish to perform?

    What type of equipment would be needed and what clinical test might be ordered/performed

    • I’m sorry. This sounds like a medical school exam question. I suggest you see your doctor to get this problem sorted out.

  7. Hi doctor.
    I was on implants for 6 months in 2014, got off in August, had regular periods until now I am 2 weeks late. Last month I had very rough unprotected sex (as always) and I ended up bleeding badly. I still had regular periods. I’m feeling pains here and there but not bad. I go by a calendar and have sex on my fertle days. My pregnancy test are coming negative?!? What’s wrong!!

    • Maybe the rough sex caused shedding of the endometrial lining so you will not see any bleeding during this period.

  8. Hi Doctor, I am a 24 Year old female and have had bright red blood after sex this morning. I had unprotected sex Monday 1-12-15 and my partner was drunk and fully came inside of me around 1am. That very next morning around 11am I took a Plan B pill, and everything seemed OK. He then came back over Tuesday Note and we had unprotected sex again this time he didn’t come inside of me so I didn’t get the pill. Then Friday nite 1-16-15 we had sex with a condom and it was pretty rough but it did not hurt. After when I used the bathroom everything was normal but about 11Am I started having a bright red discharge with some dark red (I’m guessing uiterius lininglike when girls have their periods). Its bright red and its enough to cover a whole tissue. I’m going to see if it contunines thru Sunday because it might just be the plan b pill giving me a early period, but I had just got off my period last Sunday (the day before I had unprotected sex). I’ve had two pap smears this year because I had a weird vaginal odor and was diagnosed with bacterial vagenois last summer, I was given metrogel and a pill and stopped having unprotected sex and my smell came back to normal, but it still came back the other day recently. so I think I might be allergic to semen or something. I don’t have any pain in my ovaries, or pain when peeing but I have had chalmydia 3 years ago. I asked the doctor if she could test for hpv or something because I have had an ex come inside me before and never have been pregnant.

    • There are many things going on here. First of all, you really should not rely on the withdrawal method for contraception. That means even if you BF does not ejaculate inside you, you still can get pregnant. As for your bleeding, it could be due to abrasions, the plan B pill or the fact that your period ended not long ago. You also seem to be concerned about potential infections. I definitely agree that this is possible especially since you do not use condoms all the time.

  9. hi good evening i just wan to ask like me and my husband having a sex 11 days before and then now i’ve encountered some light pinkish vaginal discharges just every morning for 3 consecutive days. please helpme if is it normal or not. thaankyou for your response

    • It really could be due to so many things like ovulation, implantation, abrasions, cervical lesions. I really cannot say if it is normal or not. You should see your doctor.
