<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just used the restroom and passed a white glob it had no blood or anything it was completely white..i am 34 weeks and 3 days pregnant and was wondering if this was my mucus plug... also me and my boyfriend just had intercourse could it be sperm that came back out?  <response>: Hi, I have gone through your query understand your concern. Mucus plug is thick mucus sealing cervix throughout pregnancy protecting it for infection. Discharge of mucus plug indicates starting of opening of cervix. It may take few hours days or weeks when labor sets in after mucus plug discharge. Usually when the delivery is in near future. Mucus plug is pinkish blood stained when discharged. AS you say, the semen along with sperms vaginal mucus can simulate mucus plug. So if there are no increased contraction pains. You need not be scared rush to your doctor. Continue your routine as usual special care for genital hygiene avoid sex. You can inform your doctor about the incidence while your next pregnancy check up. Thanks.
