Hi, i wonder if someone could shed some light on me and my gf's situation. She is the yasmin pill and had been taking it for 5 days after her period, but then she missed a pill. and we had sex five days later. We both have checked online and it says if you miss a pill take 2 that day, but she never cought up on that missed one she just carried on taking them as usual the next day after she relised she had missed one the day before, we then had sex 5 days later after her missing a pill, we did not use a back up method of contraception. She has five pills left in her pack and we did a pregnancy test yesterday and both showed negative!... Its been 8 days since we had sex when she had missed the pill, she is feeling very weak, and has flu like symptoms. Could she pregnant even though the tests where negative?
