Hi I wrote on here 5 months ago about being refused Clomid by a specialist because I am overweight. I persuaded my doctor to give me metformin as I have polycystic ovaries. I have found out today I am pregnant but I don't know how long. I had a period in November at about the right time for me (33 days after previous) but it was very light - before this it was 11 October - so what it the theory 8wks or 4 wks pregnant?
