Symptoms? Or am I reaching?

Alright, y'all, for starters, I just started using the app, so I'm not reall sure of anything...

I got my nexplanon taken out at the end of August, and my cycles have been suuuuper long. It took me 56 days to get a period after it came out. I know it's common to have a few months where things are wacky.

Currently, it's been 54 days since my last period, but I have literally no idea when I ovulate cause I haven't really been tracking long enough. I got a BFN about 10 days ago, but I've felt reeeeally weird the past few days. Tired, nausea but no vomitting and hot flashes. What do you guys think? Is it too early to test?

Help! I have no idea what I'm doing, lol.
