Period and getting pregnant

okay so I’ve been having normal periods for a while now I was on depo shot for a year but I’ve been off of it for a year and half now and I’m having normal periods. About exactly how many days after your period is over so women usually ovulate? I just got off of my period but I’ve been peeing so much and craving stuff here lately idk why. I do not have sore boobs or anything not this period cycle I didn’t. This period my blood was really dark and just lasted a couple days if that. Could I still be pregnant or could there be a chance that I’ll miss my next period?
