I went for an ultrasound, the due date is 34.4 weeks, they said the cervix is 21.8 and the lip of the mouth is 11mm, plus the head is lying low. Has anyone had something like this? Did you reach at least 37 weeks? I'm worried, I haven't slept all night, crying, my baby is wanted...I only booked an appointment with the doctor for 11, hoping I can make it, maybe it's just an error...At 30 weeks everything was great, no problems...
