New Girl! 2nd round of IUI

Dh and I have been married for 5 years and started ttc in 2012. We started seeing an OB in September of 2013 and did 3 rounds of clomid with timed intercourse, unfortunately all bfn. She recommended I see an RE, so I started seeing my RE in March 2014. They ran some lab work and found my FSH over 17... After additional tests they diagnosed me with premature ovarian Falure at the age of 23! Since then we have done three cycles with Follistem, Noveral, and timed intercourse with two cycles that looked very promising and the last I didn't respond. After all the let down and feeling extremely discouraged we took a six month break. I recently quit my job as they didn't tolerate me leaving for appt. so offten last year and I plan to take off for a while once I do get blessed with a child any way. To my surprise my cycles regulated while not seeing a doctor but I still was getting a bfn every month! We recently started seeing my RE again in May and have done one Round of IUI unmedicated, I had two mature eggs in my left ovary. For some reason the doctor said my cervix was not cooperating ( was closed and as hard as a rock ) and I have to say that was the most painful thing I've been through so far! We are getting ready for our second IUI round this weekend, I have been on 150iu's Follistem and plan to trigger with Noveral on Saturday or Sunday and follow with IUI 24 hours after. I'm excited we will have a better chance this month but at the same time I'm not looking forward to the procedure! Some have suggested an aspirin before the procedure to help with the pain. The worst part is it didn't stop immediately, the cramps that followed were way worse than AF cramps and I blead the rest of the day. Did anyone else experience this or have any advise.
