Testing on Clomid???

Mrs❤️
How many DPO do you start testing after taking Clomid? I was on 3 pills of Clomid AND 3 pills of Letrozole this cycle with estrogen and progesterone to help my lining and had to have 2 HCG shots before my trigger shot. I haven't tested the trigger but don't want to wait the full 2 weeks... when is safe to test and not get a false positive??
