I went to my drs appointment today my dr checked my cervix and told me I was 2cm dilated and 80% thinned out my cervix check didn't hurt as usual but then she said she was going to help get things moving along then I felt a lot of cramping and been having back cramps every since could she have stripped my membrane without telling me my due date isn't until June 16th! I got to finish one more week of school and make it to the end of the week for work ugghhh I think she messed up my plans!
