Trigger shot - when to test?

Ap

For those of you who conceived using Clomid, femara, etc. and a trigger shot... when did you start testing? When did you get your BFP?

I think I had implantation spotting at 7dpo and 8dpo. I’m now 11dpo. I’m afraid to start testing and get a false positive from HCG leftover from the shot. Trying to wait until 13dpo, which will be 2 weeks since the shot.
