First Trigger Shot

Hello! I will be trying the trigger shot for the first time this month and I was trying to figure out if I should test daily to see the HCG drop and *hopefully* rise again or if I should just wait the two weeks or more to let it leave my system before testing. What did you ladies (who have done the trigger shot) do? And would you do it different if you had to do it again? This is also my third month of letrozole and I was diagnosed with PCOS in October, after trying off and on for three years and nothing happening. I should be getting the trigger shot Saturday in the mail if my ultrasound is good on Friday. ❤️
