Ttc #2 after depo

Felicia • 💗💛💛💙
I was on depo a while before I got pregnant last time. I am back on it, but want to start ttc. How long after the 3 months from your last shot were your periods back to normal so I can track when I ovulate. And how soon were you able to get pregnant.? May is when my next shot is due, but I will not be getting it.
