I have spotting sometimes does it mean I am at an increased risk of preterm?

More than 3.5cms

What's the normal cervical length for the NT scan???

Mam will there be any problem my doctor hasn't seen the reports but she will today possibly.

Its a short cervix ekta.. be on complete bed rest with foot end elevation.. try not to do any type of strenous activities.. dont strain while passing stool.. drink more water and increase protein intake.. also keep a check on any kind of bleeding or leaking..
