I'm so sorry hun. I sooo know how you feel.
Have you talked to you doc about getting on Provera and then upping your Clomid dose next month? A lot of women don't O their first round of Clomid, especially if it's only 50mg. I only had 1, maybe 2 mature follicles on 50mg, and this month of 50mg, no follies at all so far. I'll probably be upped to 100mg next month.
Are you going to an OB/Gyn or an RE? I know with my OB/Gyn, I was unhappy because they wouldn't put me on Provera until I made it to CD60 without AF and they wouldn't do any monitoring at all. I feel like u/s are really important when you're on Clomid, especially with the possibility of hyper-stimulation and things like that. With my new RE, I'm really well monitored, so they know if the Clomid is working or not and can give me Provera sooner if things aren't working. And since OPK's don't always work with Clomid, the monitoring is really helpful for knowing what is going on.
If you're not getting any monitoring at all, I'd get a new doctor.
