On the 8th of march me and my gf had unprotected sex (i ejaculated inside) but she is on the pill. she was ment to come on the 16th of march and she still hasnt, she hasnt been late for nearly a year until now. she also told me recently that she had forgoten to take some pills and that she didnt take 2 the next day and didnt start a new pack. Also did take the pill in the morning and at random times everyday never at the same time. But when she was ment to come on she has had cramps for a while but no period. but last night she was sick at 4am. then at 10:30(first pee) today she did a pregnacy test and it came up not pregnant. I would also say her homons have gone off the wall but that is normal if she thinks she is pregnent. And i was just wondering if i should be worried that she still might be pregnant. Also weather it is possible and what should i do next.
