I had what I thought was my period. I had heavy spotting for two days then very light spotting that I could barley see it for 4 days with a break in between. my back has been hurting, I'm tired, my boobs hurt and I had a cold that last for two weeks. I know that it was probably my period being messed up but is there any chance I am pregnant and should take a test or do you think I'm thinking way too deep into it? I also have had the cm for the past 5 days
