I'm really worried. Me and my boyfriend had unprotected sex. I hadnt taken the pill the previous day. I've started getting clumsy with when I take my pills recently. I've been on gedarel for over 3 years. But it was this one time I had forgotten to take it, on Thursday, I had unprotected sex on Friday, and remembered to take my pill half an hour after sex. The following day I was supposed to start my period but right now I've still not started and it's Tuesday. I've been having tummy pains and I'm not sure if that's my IBS or signs of pregnancy. I also can't tell even if I am sick in the morning as this is the norm for me. Low blood sugar makes me sick a lot. I'm embarrassed and worried in case I am pregnant.
