Clomid vs femara

I got pregnant my first IUI with femara but unfortunately miscarried. I’ve been on femara twice since with no luck. We will do one more IUI before moving on to ivf but I’m wondering if I should maybe try clomid since femara hasn’t been working. I’m worried though about it thinning my lining. My RE also won’t change my dose of femara if I stay on it as im responsive to the dose but I only usually produce one mature follicle where I think with clomid you produce more which would maybe help us. We are also dealing with male factor infertility. Any advice appreciated!!!
