False Positive...?

Kat • IVF baby born 12.5.19 after: 2 years, 1 ectopic, 4 IUIs, 2 rounds of IVF & 3 embryo transfers!! 💕 Baby #2 (surprise!) due 6.2021

Long story short: I'm SO positive I had an anovulatory cycle last month - had none of my usual signs and then a real wonky "period". I've been spotting for 17 days and took a OPK last night (my normal fertile day) and it was a blazing positive, but still no ovulation symptoms. Entertained myself this morning by taking a HCG test just in case. (The test DID have a little fog to it before I used it) Can this just be an evap?? Or a false positive due to all my hormones being off from not ovulating last month?
