I haven't felt right since my appointment this morning. I went in at 11 and got checked again to find out that I'm almost dilated to a 4 and 80% effaced plus I have a bulging water bag. She said sometime this week I should go into labor. Ever since I got home tho I've felt really sick and I'm not sure why.
