Good day girls? I have stitches on my cervix, almost 20 weeks pregnant. Had an ultrasound, with the baby Glory to God everything is good, the internal opening closed, the stitches are normal, the cervix is 30 mm. Who managed to give birth in time with such indicators? The doctor said that everything is normal for now, we will keep monitoring the cervix. I'm very worried. Thanks in advance?
