21 with PCOS

I just found out I have PCOS on 2nd jan by way of ultrasound. not sure how bad yet and having blood tests done tomorrow. me and partner have been TTC for 6 months. I usually have regular periods but sometimes it's just spotting. can anyone help me because I feel like my world is crumbling around me. id just felt like i was ready for a child in my life since I've got a stable job a car a flat and a good partner and now I just can't stop crying. this has ripped us apart. what other tests will I have done? how do i know if I ovulate? thanks girls
