Hi, I had an inevitable threatened miscarriage at 22 weeks. All scans and reports were good and normal. In ultrasounds, cervical length was also normal. Maybe I had an infection as per my doctor as pus cells were increased. I have PCOS too but it was a natural conception for me. I am really scared. Is my cervix incompetence? How to detect that? Will it be same scenario in the following pregnancy. Please guide. I am really stressed.
