Hello, I am 21+ week pregnant with ivf . At 16+ week I went through emergency cervix cerclage with 2.2 cm length with bleeding . After 15 days review in fetal well being scan ie 17+ week my length 3.5 cm. Today I went through anamoly scan ie 21+ week my length is 2.8cm now with good scan reports. Post cerclage only my doctor told me to take complete bed rest n I did it so. But I thought in today's scan also my cervix length will be same as in previous scan ie 3.5 cm but it is 2.8cm now. Should I take complete bed rest based on that ? N one more thing will cervix length may decrease in next scan ie on 20th July ? What's ur opinion is tr any possibility of preterm ? For that sake only doctor told me bedrest n said tr may b / may not b possibility of preterm. Pls suggest ur opinion ? Thanku
