I haven't had my cycle since late July into August and I have been feeling sick off and on since then, get weird cramping/sharp pains in my stomach, I've taken 2 store tests and they both come back negitive. I've gotten a blood test in early September and it said no, but why does it feel like I am pregnant? I've never been before but my body is acting crazy! It's not that I don't want to be pregnant, but I've got my wedding coming up in the middle of August and I can't be yet. What is going on??
