5 days until AF

Ca

I am 9 dpo according to this app, I’m not <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> any other way. I realize it’s just a guess. But today I am experiencing mild cramping. AF isn’t due for 5 more days. I tested yesterday and it was negative. Still pretty early. Probably should wait to test again until missed period? The wait is killing me. Lol
