Internal scans in second trimster to check cervix

Ana

My consultant has booked me to have internal scans around 17 weeks , 19and 22 weeks to check the cervix due to my history of late miscarriage. But im scared to death due to internal exam tht late in pregnancy.

I got diagnosed with high gestational diabetis and reading was 10.9. Has anyone suffered from this and controlled later?
