dr said its normal,&nbsp; cut off is 2.4cm, n my internal os is closed so no need to worry

my cervix length is 51.5 mm.....is it normal or need to worry?

the cut off for abnormal cervical length is 2.5cm. however there are other factors like whether the Os is open or no or there is any funelling.

30 mm is fine. though lower normal. dont worry. <br>
if cervix shortens or opens up then its a concern. till then ur fine. dont strain. <br>

hello...<br>
30mm is quite in higher side for short cervix... The average cervix length is 4 to 5 cm, and it is expected to shorten as you get further along into your pregnancy. at 24 weeks gestation, the average cervix length is 3.5 cm. When cervical length is less than 2.2 cm, women face a 20 percent probability of preterm delivery.. so please take bed rest, avoid strenous work.. and consult doctor ASAP..

20weeks pregnant, cervical length is 30mm, everything is normal ?? or should I hv to worry??
