2.5 Cervix at 13 weeks

Je
Hello everyone,
I just saw the doctor and measured my service at 2.5. I've had two cone biopsies due to cervical cancer back in 2014. Now I am terrified that I might lose this baby, there was two options given to me. One get a cerclage which has complications and doesn't always have a successful pregnancy and the other option was getting progesterone injections. In so sad and feel that this pregnancy might not be successful. Does anyone else relate?
