Hi, both me and my girlfriend are 21 years old and we've been in a relationship for about half a year now. We decided to have sex and we lost our virginities to each other. I used a condom and everything went fairly well. There was quite abit of blood involved which i believe was from her hymen breaking and she had minimal pain. Then, exactly 5 days later, we decided to go at it again. However this time, during foreplay, as i was rubbing her, she started to bleed. She said her period wasnt due till much later and was shocked. We decided to not continue and called it off. Its been a week now and ive been checking with her and she hasnt experienced anymore of the same kind of bleeding. It was just that one time. I am very worried though. Could she be pregnant ?
