Could I be ovulating or implanting

Alexis

Today is cycle day 16 of a 30 day cycle! and I’ve been spotting off and on for 2 days like this! I’m on the last day of my fertile window but I feel like I ovulated soon as I got off my period which was 11 days ago! I’ve been having mild cramps and this only when I wipe occasionally for 2 days! I had sex 2 days after my period (cycle day 7), then again cycle day 9, 12, and 14! My period isn’t due for another 14 days! Idk maybe I’m ovulating now or it’s implantation?
