IUI pain and sperm numbers

I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> today and felt that it was quite painful :/ the doctor said my cervix and uterus are off to the left side and tilted up so it took her a bit to get yo there and she said it was tricky. I felt sharp pain during he procedure and I am still cramping a lot now (it's been about 30-40 mins). Anyone else had a similar experience?
Also my hubby had 41 million sperm with 48% motility after wash (started with 126 million and 61%), doctor said that with 41 million motility was not that much of a factor. Are those numbers good? I'm worried what cd 13 scan showed two follicles 14mm and 15mm and lining only 5mm... I've triggered 36 hours before <a href="https://glowing.com/glow-fertility-program">IUI</a> that was on cd 16 and 3 days before <a href="https://glowing.com/glow-fertility-program">IUI</a> started estradiol to help thicken the lining but feeli very negative... Any opinions?
