Trigger question

I triggered on the 28th and had my IUI on 8/30. On 9/6 I went back for blood work and ultrasound and my RE had me take 1/3 of the ovedrel injection... I've been testing out the second shot, as I had a negative test on the 6th so the full initial shot made it out of my system in that first week.

Do you think that means I should have the second shot out of my system in a third of the time?

I had positive tests so far... but I imagine they are false.

I'm just having a hard time waiting til Wednesday.
