Menopur

So hubby and I have been trying for baby #2 for 2 and a half years. We have done 3 rounds of meds. Clomid and 1 menopur shot first round didn't work with timed intercourse. Second round menopur alternating 1 to 2 shots a night for 16 days and IUI didnt work. 3rd round 2 shots a night for 16 days didn't take. They only saw one egg the first 3 rounds. I'm on my 4th round and I am now on 4 shots of menopur a night for 16 days.

I feel completely run down. Exhausted, lots of cramping, and absolutely no energy what so ever.

I was wondering if anyone has ever had any success on Menopur? Also if anyone has had these symptoms while on Menopur?
