Alright... I'm supposed to test tomorrow... AF is supposed to start Monday... I feel bloated and I'm having some cramping but I don't think it's related to being pregnant to be honest... my lower back has been killing me today and I feel so irritated about everything... I just wish I could be pregnant so I can stop all this guessing and finally be happy!!!!! Do you think any of this could be a sign of pregnancy or just AF annoying me a few days early??
