I've just had my 20-week ultrasound (actually at 21+2 weeks), and everything was, thankfully, normal. One thing though, the sonographer said that my placenta was covering my cervix, and I would have to come back for a 36 week ultrasound to check that it had moved up and out of the way. The doctor said that there was no risk to the baby or anything, but it might result in a caesarian, and I'm not sure how I feel about that. Has anyone else had a low-lying placenta, and can tell me what happened? Thanks for any help you may be able to give me.
