Super early, only on cycle day 20, maybe 5 DPO but felt some cramping and decided to just test

Edit: when i conceived my son who’s 2 1/2 now, it was from watching my ovulation by cervical mucus, which If that’s how i measured DPO it would make today 8 DPO. I’ve always assumed i ovulated on day 10 but had a <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> tell me i ovulated on day 15? Unsure! Will test again in a few days!
