Two months ago I was feeling nauseous and lightheaded for two months straight (I was eating normal periods). Then At the beginning of October I got my period but it was very light for like 3 days (usually that’s how long they last). A week later or so I started getting cramps again and have been still for the past 2 weeks or so. But there’s no period yet & plus it’d be two periods in one month. I am on birth control but this has never happened before. My breast feel sore and hurt a bit when touched right now. I still get nauseous. Specially when I’m inside a car sometimes and I get lightheaded still. I already took 2 pregnancy test but both came back negative. (Took them at the beginning of October, after my light period) help!
