Pregnancy or PCOS bugging out?

I’ve been off BC since September and have regular periods and regularly ovulate since. I’ve been TTC since September as well.

Some early pregnancy symptoms have been my normal PMS symptoms: nausea, constipation, boob/nipple sensitivity. This month, that’s happening again, but I’ve also had CM like crazy for the past week and a half (like, I have to wear pads amount of CM) plus AF is 2 days late (per the app but my app is usually a day off in its calculations). I took a test this morning and got a BFN. If AF still isn’t around on Friday, I’ll take another test. Anyone else have this sort of stuff going on and be pregnant or is this PCOS deciding that this month would be a great month to mess with me?
