I feel like i'm going crazy!!! So AF is due next wednesday but for about a week an a half i have been having symptoms. My boobs are bigger, heavier, sore and covered in veins! I need to go the loo all the time and have lower back ache. I have took a test and its a BFN but i know myself i feel different, is it all in my head or am i testing too early? Would appreciate some advice ladies thanks x
