<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, myself and my boyfriend had sex last week, some of it we used condom for some we didn t. He didn t come, would there be a chance I d be pregnant? Last 23 days getting very light period? Not due until next week. Don t know this guy too long..as in couple mths... ? Roisin  <response>: Dear Rosin, Since during some sexual contacts, he did not use condom, the probability of pregnancy does exist. Though he had not ejaculated inside your vagina, deposition of pre-seminal fluid pre-cum cannot be excluded. Pre-cum does contain some sperms which are capable of fertilizing an ovum. Pre-cum gets deposited without any sensation to a man. Please find out the evidence of your pregnant status by:1. Perform Beta Chat Doctor test on your blood 10 days after the last unprotected sex. 2. Alternatively, wait for your menses to appear. Light bleeding may not be a true menstruation. If you get good menses, you are not pregnant. If they are delayed for more than a week, perform pregnancy test on overnight morning first urine sample; earlier the test may report false negative results. If you are not sure whether you have missed period or not due to scanty bleeding, you may perform the test 3 weeks after the last unprotected sexual intercourse. I hope this will resolve your dilemma.
