im 30 with pcos , im taking clomid again after losing 2 stone a few months ago , i started taking day 2 off my 33 day cycle im now 8 days late with 2 negative hpt , could i still be pregnant or is it my mind playing tricks , im very moody and feel really down , i have tryed clomid before a few years ago but did not ovulate at all but i did bleed after , is it just to early or does this happen alot x thank you
