IUI#2 fail

ER

Well I'm truly stumped. I had 5 mature follicles (over 18) on cd12 ultrasound. lining was 8.5. estradiol 1340. we triggered on cycle day 13 at 4 p.m. and my doctor had us do the <a href="https://glowing.com/glow-fertility-program">IUI</a> 24 hours later cycle day 14 at 3 p.m.. my gut feeling told me that this was too soon that I should have insisted on waiting until the 36-hour mark. So my question ladies, is have any of you who have done an <a href="https://glowing.com/glow-fertility-program">IUI</a> at the 36 hour mark from trigger seen success? DH count after wash was 29.5 mil with 70% motility. We BD same day of trigger and 2 days following. Just really stumped and at a loss for words. DH and I have no fertility issues. so I'm questioning is it my lining, timing of procedure, Not enough CM? And advice? Thanks in advance TTC since January. Started at 100 mg of clomid but this cycle doc increased to 150mg.
