My cycle comes on every month , but I haven't seen one since November 3-8. (went off on the 8th). I've been taking gain weight pills and have put on a couple pounds since october. I googled to see what are reasons for late periods and those were the only 2 things that related to me. I've been having unprotected sex with my partner since november. I've picked up weight and mood swings, and my stomach just has a form that doesn't look like weight gain, everyone says take a pregnancy test, bt I have 3 other kids and I was at least a Lil over a mnth to even be able to tell all my pregnancies and all my tests say neg. Even when I am (smh).
