16dpo…?

16dpo..? I never got a peak this month, I got low , then “high” the next day, then low again the day after. I quit testing after that. Assuming I just missed my peak and ovulated that day, af should have came two days ago.. I’ve been cramping like usual leading up to af for the past 4 or so maybe even a tad more than usual. Boobs sore like pre-af. Should I test or just assume that maybe I didn’t ovulate when I took my opks and had a second surge which is why af is late? I’m just scared to test honestly 😢

I’ve been pregnant two times and not feeling some of the symptoms I felt then, but they both ended in a very early miscarriage.
