What do you think helped you ovulate?

Sorry in advance for the long post! My husband and I have been “not preventing” for more than a year, and it’s time to start actually trying. I’m about to start provera because I haven’t had a cycle since July. Last time I took it (way back in May) I did not ovulate. My dr doesn’t want to give me chlomid without my husband first having a semen analysis. Well, the analysis is expensive and not covered by his insurance until next month. So, my question is, did anyone do any natural method (or at least bought over the counter) that you think helped you to ovulate? Obviously I know nothing is guaranteed to help, but if there’s something some of you tried that I could give a chance this month I’d like to know what you did. Thanks!
