honestly, i know so little about all this. but i was in basically the same place, trying to figure out if there were some relatively low-tech options for my last couple tries. dumb luck i chose femara and didn't really consider clomid. my understanding is they work in a similar way, but femara doesn't affect the lining. i tried it one time and got 2 follicles going instead of 1. as a poor responder, i always thought doubling the odds each cycle was pretty good. you might ask your RE about femara as an alternative and compare the two options.
good luck, i'm rooting for you...!
