Trigger Shot and IUI same day?

Today is CD14. I ovulate on my own and typically get a +opk CD 14,15, or 16. I’ve been testing “high” on the digital test with EWCM the last few days, as well as early this morning. 2 follicles this morning measuring 20 and 22mm. This AM, my doc administered the trigger shot, and I had the IUI just 3 hours later. Based on my pattern, I anticipated that I would probably get an LH surge on my own today anyway, but I thought it was weird that we did the trigger and IUI on the same day instead of tomorrow. My doc said they usually do a scheduled IUI the next day after a trigger. However, since my follicles looked ready, he said it’s not unusual to trigger/IUI same day. I did not get blood work done. Took Femara and this is my first IUI.

Has anyone else had this similar scenario and had success?
