Is it possible to have PCOS?

I had a miscarriage in April 2020 and I got my period after my miscarriage until August. August 14,2020 was my last period and now it is 2/25/21 and I have yet not gotten my period. Also me and my partner are not having protected sex but I haven’t gotten pregnant since my first and only miscarriage. So now I wonder if I might have PCOS.
