got mine prego while on and i was 46 yrs old.. and had had a reversal..

my sperm count was 100k which if you ask a fertility doc that means i'm basically sterile..

50mg clomid for 30 days and i was shooting 6 million.. and bam, she was prego..

with that said.. have you had your thyroid tested?? if it's slow or high (Hypo or hyper) it will be more difficult for you to conceive..
