After a little over a year TTC, polyp removal surgery, and our first IUI, I am wondering if I have finally got our first real BFP.

I did an IUI on April 14th with an Ovidrel trigger shot in the evening of the 12th. This morning, I got a positive on a First Response (with the rounded handle) and a digital. Is it possible that this is the real thing, or is this the trigger shot still in my system?

Thanks so much in advance!
