Birth control

Just had a baby almost 3 months ago and I got on the pill right after. I was previously on the implant before pregnancy. I recently heard that you could get a patch I didn’t even think that was a thing, what are yalls thoughts on the patch and experience good and bad !? And does anyone take this birth control pill I don’t even know much about it this is the one I’m currently on, and it’s got my periods WACK I’ve been on my period 3 different times this month and that’s never happened
