Ok so I'm not on birth control and my boyfriend cums in me every time we have sex. So far I have yet to come up positive but I'm due for my period soon and I'm not having any sort of pms how I usually do. I was gonna wait a week after to take a test but I'm want to know if I'm pregnant or not now. I keep having hot flashes, headaches, aches and pains, my breast are almost constantly sore and I get nauseous along with cravings. My boyfriend just thinks I'm lacking vitamins but I have a feeling I'm pregnant. Any ideas what could be going on?
