I don't know if the suture actually strengthens the cervix or not, but am intrested in this thread as I am currently being scanned for an IC, I am already on the low end of the scale, first scan was 2.5cm and the second was 2.79cm, not very good for the start of a pregnancy, so hoping that there is a good length in the next scan next week.

What cervix lengths were you getting at each of your scans?
beema, not sure if u meant me or not but at 12weeks i measured 2.5cm like u....
i was put on bed rest for 2 weeks and ended up at 3.5cm.... so the bed rest was relaxed but still the "be careful" orders...
follow up scan at 18weeks and had hit 3.4cm so OB was happy....
when in at 20weeks and had dropped back to 2.4cm..... full bed rest again...
21 weeks had a off day called OB and went to the office and sure enough my cervix had started to give in and my waters were buldging.....into hospy on total bed rest, no getting up for anything, ended up with an infection and delivered at 22weeks.....

my OB has advised my cervix is in a cruddy state.... he said he would have expected ot see someone who had had 6-7 terminations, or cone biospsies done or multiple D&C's with a cervix like mine but ive had none of that......im just one of those unlucky ppl with a cr@p cervix.....

ill be having a stitch put in at 13 weeks when i get preg and then removed at 37weeks....

HTH helps

feel free to PM me if u need to ask anything!

good luck for ur scan hope all is travelling along ok!!!!
