Last round

I've decided that this past round of clomid (#4 100mg) will be my last... the mood swings have been intense and the hot flashes worse... I can't sleep and I can't relax.. I don't like how it's making me feel and I'm worried it's thinning my lining (last to periods have been really weird) I'm seeing for the first time a fertility specialist in a couple weeks- any suggestions on other things we can try? Hopefully this round does it but just in case....
