I was diagnosed with PCOS about 6 years ago. Ive been on birth control since. On january 1st i had what i thought was my period, i had some brownish and some pinkish spotting that lasted more than a week. Since then, i havnt had my period, so 3 months! I have taken multiple home pregnancy test and they all came back negative. Lately i have bad lower back pain, fatigue, migrane-like headaches, and often feel lightheaded. On the other hand ive lost 45 lbs in the past year and i sometimes go a couple of days without eating. I have almost zero appetite. I just dont know what to make of any of this. Maybe i had a miscarriage back in jan? Maybe i have ovarian cycts? Maybe im pregnant? Please help! Freaking out over here!
