Ovulation on Clomid

A little back story: This is my third round of Clomid. First round at 50 mg did nothing, so I asked them to bump my dosage, two cycles later i took 150 mg and had three matured follicles. I was unsure about doing the trigger since I typically don’t have issues ovulating but I ended not getting a positive opk around the time I usually do, so I opted for the trigger shot. I didn’t get pregnant and my doctor thinks I did the trigger too late. So this month I took another round of 150 mg and have my follow up appointment on Monday to see how many follicles I have.

My question is when did YOU do the trigger shot?

If everything goes well, I was thinking of doing the trigger on Tuesday so I don’t miss my window.

Thanks!
