No OV 3 months post BFing and TTC

hey ladies i wasn't sure where to put this thread but TTC seemed the most obvious..

I have a 14 month old LO and i stopped BFing her in August... since then my AF's haven't returned and i don't seem to be OVing either..

I've been POAS for the last month and nothing.. i do have v mild PCOS and have lost a fair bit of weight and am wondering i it could all be linked?

I'm taking Angus Castus and have been for 1 month now but can't think why my AFs haven't returned yet, one or two months i could understand (i was never clockwork)

Anyone else had similar?
