I had a follicle scan this morning and I had an 18mm and a 19mm. The doctor said to trigger tomorrow night (Sunday) and <a href="https://glowing.com/glow-fertility-program">IUI</a> Tuesday. My opk is almost positive and I don't want to miss it. Should I call them or should I just do what they say? I know they aren't positive but the bottom is close. Top is 9am and bottom is 1:30pm
