Ibuprofen and IUI Help

Today I did IUI for the first time and before the procedure I asked my fertility doctor if it was ok to take ibuprofen beforehand because I was having bad ovulation cramps. They said it was perfectly fine but not to take any after the procedure. However, afterwards I looked it up and most sites and people say NOT to take ibuprofen because it affects fertility. So, super confused but I know I should trust my dr. Any women have similar situations or knowledge on this? I had two really good size follicles on ultrasound. I’m just hoping I didn’t ruin a good chance today and trying not to stress. Easier said than done.
