Who would be interested in an all girls groupchat?

I feel like I’m learning all of this for the first time again. I was on the nexplannon from the age of 15-21 (I’m 22 now). So for 6 years I didn’t have a period and now that I’m off all birth control I feel completely lost and I don’t know anything about periods. And let’s not forget about everything that comes along with it. I just feel completely lost and I don’t know anyone else who’s been through this, or or anything similar.
