HELP!!!

So I’ll try and make this post short but I can’t promise you anything

So I have an appointment with my doctor for my CD12 ultrasound to see how my eggs look and then trigger to inseminate Monday. (First IUI).

HOWEVER!!

I’ve been cramping on my left side today and feel extremely tired. Basically AF symptoms so I decided to take an opk and I got a blinking smiley face! Cm look like egg whites as well.

This app says that I am supposed to ovulate Sunday and another app says Monday. Usually when I have these symptoms it means the next day or two I will ovulate. If I’m ovulating on Saturday would the doctor inseminate right then and there? We paid for a trigger shot and that would mean we wouldn’t use it. I am going to take another opk tomorrow and see what I get but could it be possible to ovulate earlier?
