hello there, i had a lap and dye in march, and as it went very well the doctor decided to put me on clomid. well i've been on it 2 months, the problem is that this month i haven't had a period yet, i was due on the 22nd of may, and i'm now 6 days late. i've had 3 pregnancy tests which have all resulted negative. my doctor said to wait another week and then try another pregnancy test... has this happened to anyone else? am i pregnant? is it a side affect o clomid.
