Sorry to hear that, hun.

What dose were you on? Maybe a higher dose will work better for you? A close friend of mine has annov PCOS and she didn't O her first cycle of clomid, but she O'd and got a BFP on a higher dose the next cycle.

If the clomid doesn't work for you, you could ask your Dr about Femara. It's not as common, but I know some doctors have started prescribing it instead of clomid. Otherwise you start looking at injects.

And if those options don't work, then (and I hate to say this) you probably need to work at losing some weight (depending on how much overweight you are). Some women just simply won't O unless they do that. I know it's hard and it's something I'm struggling with myself (I may well weigh more than you, so I'm not some skinny chick lecturing you about being overweight, I do understand and I'm definitely not judging you), but I have another friend who just wasn't O'ing no matter what meds she used and she lost some weight and got a BFP. Each of us has a different threshold at which our body will stop O'ing and, as unfair as it is, someone bigger than you can be very fertile while you don't O, just because their threshold is higher.
