5th IUI today - hopefully it works as i think this is my last :(

I just had my 5th <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle with Gonal F injections and Ovidrel trigger shot , today starts the two week wait.  
 My cycle went unusually slow this time around.  I had one left over follicle from the last <a href="https://glowing.com/glow-fertility-program">IUI</a> that was at a 44mm but shrunk did to nothin.    I didn't end up triggering until Cd 15 (normally happens at Cd 11-12).  My estridol level was at 1464 (highest it's ever been was 800).  I have 6 follicles, 4 of which will be ready for insemination.  My husbands sperm count was at 77 million which had been his best yet, usually we are anywhere from 8-44million. 
I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> today, Cd 17.  was told there is a risk of multiples (had the risk of multiples before and not one took...bring on the twins!) and OHSS.  the OHSS freaked me out but I was told how to help prevent or lower the severity of the OHSS and what to watch for.
I have been very exhausted and bloated ...very uncomfortable this cycle. I assume for yo the high amounts if meds and the estridol levels.  
anyone ever been on the same boat as far has levels, follicles and sperm count and got a BFP?
