My Gf told me to ask this question here. Last friday was her 4th day after her period has ended. We had some anal and oral intercourse that day. Later on Sunday morning, she found some spotting on her underwear. She got confused at first. The blood was just three little blood stains and it stopped. And yesterday, marks her 6th day after her period has ended. Then she realised the spotting came again. It stopped again yesterday. Now she got really confused and is afraid that she is pregnant. Can someone who is an expert explain this situation for me and my gf? Thanks!
