I've never heard of Clomid stopping your periods for a few months. Birth control yes but Clomid is a fertility drug that is supposed to help your body ovulate, therefore you get a period when on it.
I too have high fsh and started ivf meds begining of march but it was cancelled due to poor response and i haven't had my period still. I'm curently on day42 also tested neg i'm waiting for it so we can try again sorry i know that doesn't help much just wanted to share so you don't feel like the only one
i also have high fsh 13.9, and they told me that the fsh does not affect the preg test results.. however, if u took any meds (clomid etc) in the last few months that can stop ur periods for a few months. how high is ur fsh..
