URGENT!

So I’m freaking out...I went yesterday and had my vaginal ultrasound and the doctor said I had one good follicle and was ready to move forward with the IUI. I’m suppose to have my trigger shot in an hour and I just went to the bathroom and had a TON of cervical mucus. I just took an opk and it was negative but the light was a lot darker than it has been and I know it’s better to do in the morning so I don’t know if it’s validated. My question is should I still do the trigger shot or should I call my doctor? My wife says I’m overreacting and I should just do the shot anyway but I really don’t want to mess up our chances this month. Anyone been through this before? TIA!
