I pretty intune with my body so I notice changes and I have noticed in the last three days that my breast are swollen and super-sensitive all over and it is not even near my time of the month, I have another 13 days still Aunt Flo comes. I am also feeling foggy-headed and tired more so then normal and nauseous and bloated. Could this be pre-menopause or early signs of pregnancy, if I'm preggers it would be like only 3 to 4 days at the most. I didn't think I could get pregnant but it just seems odd that my breast hurt like this, beyond the tenderness they feel before my period. I mentioned pre-menopause because I am 37.
