Blayz- the day i found out i was pregnant with my third child i got AF pains and an hour later i found out i was pregnant. I got alot of pains and stuff in the first couple of month with all my kids. Its cause of all the changes inside your body and everything growing and adjusting. I dont know if IVF is different to naturally falling pregnant,im pretty sure it would all be the same. How many more days do you have to wait>???
