Help a girl understand


I'm TTC.

I got my nexplanon implant out July 24th. I had a heavier longer period. Then a second period much closer than I normally do. I believe my body was just trying to regulate after getting off BC?

I got OPK sticks to try to figure out when I'm ovulating. Did I ovulate the 21st? My CM didn't look fertile, I think?

The app kept saying I was ovulating the 19/20 but my sticks weren't darker than the control line those days. Does this mean I have longer cycles?

I feel discouraged that I don't understand what my body is doing or if I'm timing sex correctly.
