False Positive

Stormy • Stormy, 29 🌻 Divorced. Baby #1 born 4/19/18 after 19 months TTC with tubal insufficiency! Baby #2 born 01/26/21 after issues with ovulation and an incompetent cervix.
I got this false positive on a FRER. I know it wasn't a chemical pregnancy because if it was, my hCG level wouldn't already be back to 0.0. I'm so frustrated...
