Anovatory Cycle- Frustrated!

I just got my 21 day lab level back and it was a 7.7 (no clomid this cycle) which my Doctor indicated was anovulatory. I am just so upset and confused at this point. We have been trying for 2 years, have done 3 rounds of Clomid, had to scrap a cycle of IUI because of hyperstimulation, and all the tests up to now have come back negative for issues. I just had surgery in January for endometriosis, and still no positive tests. We have seen 2 different fertility specialists and they have recommended IVF as our only option. I don't mean to sound whiny, I am just so mad that no one can seem to tell us what's going on. I feel like we're running in circles! Anyone else going through a similar situation? We have an appointment for April but IVF is a whole other level (especially in case there are other options!) that we're willing to do if need be, but it's so daunting.
