Marginal Placenta

thumper11

I found out at my 20wk u/s that I have a marginal placenta.  The doctor said that meant my placenta is 3 cm away from my cervix...  It makes me a little nervous.  She said there was nothing to worry about and that it should correct itself by 32 wks.  Only thing is is if it doesn't we have to schedule a c-section.......:O I do NOT want one of those.. at all!!!!!  So no sex for me and the husband for 12 wks at least. 

Has anyone else had experience with this at all?
