Need some reassurance guys. This is my 3rd pregnancy .I've had 2 miscarriages before,first one was in the 2nd trimester and 2nd one was at 5 weeks . In now pregnant again and hve been having 2 weekly ultrasound up to today. I'm officially 27 weeks tomorro. However I did my last ultrasound today to e reviewed in Wednesday and it was always between 3 .1 to 3 .5cm. Last 2 weeks it was 3.5cm. Now today she was like it dropped below 3 but it's more than 2.5. She didn't give me the exact number . I'm paranoid as it's too late now for cerclage . I can't wait for my visit on Wednesday. Anybody else here goin through the same thing with cervix length
