IUI difficulty inserting catheter

L

Had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> today. Doctor had trouble passing the catheter through my cervix, so he ended up inserting it as far as possible into my cervix for the <a href="https://glowing.com/glow-fertility-program">IUI</a>, but not fully through my cervix into the uterus cavity. He said the sample still went in well, but obviously would rather have the catheter fully inserted. Anyone else had an experience like this?
