Still no period after stopping breastfeeding


Hey all.

I had my 2nd baby (a girl on 8/10/18) I breastfed her til the beginning of july 2019. I'm one of those lucky people that dont have a period while breastfeeding. Well I still have not had any sign of my period returning. I still have a little milk but not much and they shrunk way down. I haven't had a period since I got pregnant with her in Nov of 2017. I have some left over progestin pills of 200mg I'm going to take for 10 days to see if that works. I also keep getting crazy hot flashes. Anyone else experience this? When I stopped bf my son if came back 3 days later. I'm going to wait a few more months and see a dr if if doesn't come back. Any advice?
