Yes - i believe pregnancy does cause OV tests to be positive, so the HCG trigger shot should do the same.

With HCG, get it then forget it...It takes two weeks to get a clear result. It's tough to wait, but in the end it's the only true result you will receive.
I used to buy tests after HCG just to see the positive, it never was.
HCG does work, it gives the doctor an idea to ovulation and fertilizes every egg to make it viable.

hcg shot can give a false positive in a pregnancy as the hpt kits measure hcg levels that only pregnancy produces.Not sure about opks
