I'm 15 days late for my period. I have PCOS, but I haven't changed anything and my periods have been like clock work. I've taken a lot of tests and there all coming back negative. The doctor said I have to wait a month till they'll do a blood test. My boobs and nipples hurt so so so bad! Like they've been waking my up at night from the pain. I've been eating weird things, like super strong food cravings and I cant shake them. I had aches in my sides and lower backs, a muscle kind not a period cramp. I'm just not sure what to do, or what to say. I just want to know either way!!!!! My husband and I have been ttc for over two years and it's all I wanted for Christmas... to be pregnant finally!
