Thanks for the answers Aw. I don't think the Metformin is working for me. I did have regular AF after coming of da pill in June 2003, which was odd cos i have had PCOS since i was 16. Then all of a sudden, after 5 months of Metformin, AF stopped. I had to take Primolut to get a bleed in order to start Clomid this month. I have been thinking that my excess weight is the reason why i haven't fallen pg yet. Since October 2003, i have only lost about 5kgs. I feel (even tho i know its irrational) that not having a baby is my punishment for being overweight.
