cervical cerclage

i had a previous 2nd tri miscarriage in 2023 where i gave birth the baby suddenly. im currently in my 2nd tri again and the doctor suggested cerclage. however i have been going to the hosp for every 2 weeks to get my cervix check and the cervix is not getting shorter. im on utrogestan since first tri. should i go for the cerclage or should i continue 2 weeks check up on cervix and continue utrogestan. i feel like this time, i have a better mentality and healthier pregnancy. im in dilemma.....
