Hi, I and my girlfriend had sex 10days ago and she complained of pain in her lower abdomen yesterday and she vomited a couple of times too it seems. As far as my memory goes, it was a fortnight that her periods were over and we had an unprotected sex, but I had not ejaculated in her vagina, and also we had a foreplay session before getting into the act. Today She fears that she's pregnant. Can it really happen so that she may be pregnant? what are the possible probabilities?
