So I am 37 weeks 3 days... I'm certain that I lost my mucus plug about 3 hours ago. I was dilated 1cm on Wednesday. Ive been having lots of pressure since Tuesday night, and period like cramping until today.... I still have the cramping, but now my stomach will get tight when I get the cramps also. This is my first pregnancy, so I have no idea what to expect as far as contractions.... Thanks in advance.
