About a month ago, I had spend the night at my girlfriend's house and we had only done sexual activities with our hands and mouths and such. I ejaculated and did not urinate afterwards. The next morning, roughly 7-8 hours after my last ejaculation, we had begun fooling around with genitals touching, specifically the tip rubbing against the surface of her vagina. I would constantly wipe off any pre-cm as I had known there was a chance that it could contain runoff sperm from previous ejaculations (But have read that Sperm cannot live very long outside body? Not sure if this is accurate), but would make sure that my penis had nothing on its tip before going near her vagina *she was on top of me during this*. Afterward, we had decided to grab a condom and proceed with intercourse *both our first time*. It was a lot of playing around, which ensued putting the tip actually inside of her and even more inside, until we had tried to put all of my penis inside her, which unfortunately, tore her hymen, causing her to bleed a good amount, which caused us to stop *again, condom was on for this*. She went to the bathroom and urinated, flushing most of the blood from her system, and maybe, I'm not sure, but maybe flushing any sperm out if any had been inside? This was a week after her period occurred. 3 weeks later she had come to my house and was expected to begin flow thursday, but is usually late by a few days, expecting to actually begin her cycle saturday-sunday. On saturday she still had not started and we had sex *no hymen tear, no unprotected contact, condom was on entire time penis was in contact with her*. Sunday she still had not started, and now it is thursday night, a week after her cycle's supposed start, and still has not begun her period. She is not feeling any known symptoms of pregnancy, but is extremely stressed and worried, as am I. She feels some symptoms of PMS but still has not begun. I bought pregnancy test for her and we plan to do it friday and Sunday to see if she is. My question now is, what is the likelihood that she is in fact, pregnant?
