1st pregnancy miscarriage at 20 weeks, baby born alive, suspected incomptetant cervix.
2nd pregnancy, stitch at 12 weeks no complications, dd born at 38 weeks.
3rd pregnancy, stitch at 14 weeks no complications, dd2 born at 40 weeks.
4th pregnancy, stitch at 15 weeks heavy bleeding after and miscarriage four days later - also had measles at the time but baby showed no signs of being affected by the virus so dr's think the stitch caused it.
5th pregnancy, no stitch scan every two weeks, 29 weeks now and all is well, as my cervix had grown between the last two scans I'm considered to be safe now and don't need to be monitored for cervical length any more.
I'll never know if the stitch helped with the dd's but it certainly gave me peace of mind, but after my mc in July I decided to try a different approach. My cervix is probably in a worse state now than it was in my previous pregnancies as I gave birth to my baby through the stitch as there was no time to remove it.
