I took clomid 50mg and have 4 follies... and am wondering will they ovulate? is ovulation certain after a size? this year I didn't ovulate at all after getting pcos and misccarying but before then my periods were like clockwork 32-36 days apart but every month. Snow they're 35-70 days apart and a mess. How can I know if I will ovulate and when? I've been doing opks this whole week and they don't look as strong as they used to last year when all was well. help me girls! I really want to get this right.
