I feel broken

TW: Miscarriages. I have a 5 year old daughter I conceived no issues. Then I had a traumatic miscarriage in October of 2020 with my ex husband that really kicked off my infertility issues. I didn’t have a period for 6 months until I was finally out on metformin and diagnosed with PCOS in July of 2021. After 3 months of still not regular periods I was put on provera and clomid. I got pregnant my first cycle in late December and miscarried at 6 weeks in late January 2022. We never recovered and our marriage ended shortly. I have a new partner now and we have been ttc for 3 months and nothing. Negative after negative. I feel broken because I know it’s my fault. He has no children so this would be his first and I know it’s my fault he’s disappointed every month 😭
