Hallow Dear, Your boyfriend has entered his penis inside your vagina for about an inch length. So your hymen must have been ruptured. This caused the bleeding after the act. So you have lost your virginity. It is possible that during first act, the hymen is severed partially and will get completely ruptured in next few intercourses. During the 10 minutes of his penis inside the vagina, even though he did not ejaculate inside the vagina, he might have deposited pre-ejaculation secretions (precum) in your vagina. Precum is deposited without any sensations unknowingly. Precum do contain some sperms which can cause pregnancy. This incidence took place about a week after your menses were over; i.e. around Day 12-13, which is very much near the day of ovulation and hence within fertility window. So the chances of pregnancy are very high. Since, now it is about a week that you have missed your period, you may perform pregnancy test on your overnight first morning urine sample to know about your pregnancy status. Alternatively, you may opt for Beta hCG test. Levels below 5 mIU/ml are found in non-pregnant state while values above 25 mIU/ml are diagnostic of pregnancy. If this is unwanted pregnancy, you may go for termination of pregnancy up to 9 weeks of gestation. I hope this helps you. Dr. Nishikant Shrotri
