Test strip positive before First Response?

An

I don’t know which is the proper group to ask this question. I hope this is okay.

A week ago I had a strong positive ovulation test, and a positive PREGNANCY test. I got blood work done and my HCG was “less than 1”. We did the baby dance 3 times since I did have a positive ovulation test. It’s now 8 dpo (if I was actually ovulating). I took a first response this morning and it’s stark negative. I took a test strip this afternoon and I feel like it’s pretty positive. Has anyone else had a test strip be positive before a frer? I can’t believe how many false positives I’ve had the past couple months. I’m 99% sure this is another one 😕
