PCOS and concerns

Hey guys, so I’ve recently been diagnosed with PCOS.

I had a miscarriage In September this year, and they did not do a DNC and a month later I found out I have BV & PCOS.

My main concern is how this going to affect me and my body, what should I do? and it’s so hard to get pregnant already. IP just feel devastated time and time again. Any advice?
