This might be TMI but I'm starting to worry, I've been having so much pressure down there and i have like a horrible throbbing pain down there it feels like I had horrible rough sex and am sore ... Is this a sign of anything ?? Should I call the dr ? Am I dilating or something ? I don't feel cramps or contractions just pain and pressure...
