Cycle canceled

Well i got bad news today that my iui cycle is canceled and I'm super upset about it. Its a long and confusing story, but the issue is i have 70 antral follicles on one side and 49 on the other. So they were unable to get a dominant follicle from me this time. I'm wondering if anyone has had a similar experience? Last iui i had was April/May of 2017 and we managed to get 2 mature follicles but it came with like 10 gonal injections and 2 or 3 hcg shots before my trigger and i was almost canceled but that time i only had around 20-30 antral follicles. I start provera tonight so we can try again but i dont even know what to think I'm so upset that i had to cancel and I'm even worried i wont be able to do iui because i have so many follicles and i read even with ivf you have to cancel if you get too many follicles because of OHSS
