Not really feeling like a "woman"😞

So..me and my partner have been together 5yrs this Nov! Was on b.c. 3yrs...just recently gotten off the nuvaring this past march....also I have pcos and miscarried last June (didn't know I was pregnant)... Always been told carrying a child maybe hard for me... Feeling discouraged to the point that I (found out my partners sister was pregnant today) am very jealous/emotional...any helpful advice on any area? Open for any suggestions...
