I have been taking alesse for a couple of months now but my last period was odd. It came about a week earlier lasted 4 days stopped and then when it was time according to my pill schedule it started again .I can't remember if my period before that was off but I sometimes miss a pill. I have been showing signs of pregnancy for about a month now, fatigue, sensitive to smells, i've been gaining weight but it looks like im already showing like im 3 months pregnant and I recently lactated from one of my nipples. I took a home pregnancy test 2 days before my next expected period and it showed negative. Would i be having a early pregnancy so the results are wrong (i just dont think all this could happen within 3 weeks) and could I be over 4 weeks pregnant? or is me taking my birth control messing with my harmones?
