Girls who ovulate right after period❤️

Girls when do you test? I’ve only just really realised that my app may be wrong on ovulation as I’ve had all the signs right after my period I.e white CM, migraines and stingy nipples, my periods due in around 12 days I decided to take a test today not really hoping for much but yeah, it was of course NEG I was gonna test again in the morning I should be about 10DPO if I ovulated when I thought I did 🥰 any advise? My test I took earlier now has a second line but it’s gray and I’ve heard that’s an Evap? So no babies here yet😂
