Hey, all!

I am very new to the world of TTC. My first daughter was a surprise, but we are now ttc for baby #2! I got my nexplanon removed a couple of days ago, but I have no idea where to begin. I havent had a normal period since I got pregnant (almost three years ago) between pregnancy, birth, and then immediately getting nexplanon. How do I begin to track when I could be ovulating or not? Should I expect a random period soon now that my BC is gone?

Thanks for the advice in advance!
