I have never had my period start early. Late yes but nothe early. It started off just brown I went to the bathroom again and there was some red. Am I starting my period? I'm trying not to get my hopes up, but my ovulation day was 12/24. On the 26 I ate my usual lunch and threw up. Been having frequent headaches. Nauseous sometimes. Mood swings. Tender breast. I'm hungry more than usual. I took pregnancy test 1.2/1.4. Both negative. Could some one please help me.
