Danstar - I'm booked in for a caesar in 2 days due to placenta previa and I had a scan just after 37 weeks to doubly confirm that the placenta hadn't moved. If nothing else, it put my mind at rest that I explored all of the options and at least got to make an informed decision in conjunction with my ob. I felt like a bit less of a passenger IYKWIM?

If you suffered PND with #1 I guess they would consider you at risk of going through the same again, so if you asked for a scan to put your mind at ease I'm sure you wouldn't have any trouble getting it. Has the dr given you any indication this is another big baby already? On the other hand, if they do a scan and they think the baby is not as big, have you thought about whether you're up to attempting a vaginal delivery?

I hope you find peace with whatever decision you make, and I'm sure without the stress of the emergency situation you were in last time you'll be a lot better off!
