Hi Saram,
I was induced with DS 10 days early because there was a slight leak of my waters, and the doctors said there was a greater chance for infection if I just left it. (Thinking back now, Im not sure why they didnt just monitor me or keep me in hospital for a few days, rather than induce me that early). No my DS was not posterior, he was 9 pounds and just had some trouble coming out, hence me having a vaccuum extraction.
Hope everything is going well with all of your pregnancy's!
