I went to the ob yesterday

about my stomach cramps, back pains, vaginal pains and pressure. I almost positive it was just Braxton contractions but I was unsure since i went on meds with my last pregnancy to stop contractions. Anyhow, he did an internal ultrasound and said everything looks good. It is more than likely being baby number 4 the pains are starting sooner since everything is already stretched and what not. I am getting really bad vaginal pains the more I'm on my feet. I am even having more goopy discharge, which he said is normal. Has anyone ever used one of the support belly bands or braces? I wonder if that will help my pains when up?
