Pains up inside my vagina what is this !?

Mandi • Married in March ... Just found out pregnant in October
The doctor says contractions you feel in your abdomen area. So I don't think it is Braxton Hicks or contractions. I have been having bad sharp pains up inside my vagina has anybody else experienced this I am 38 weeks pregnant 50% of faced and 1 cm dilated do you think maybe that is what I'm feeling the dilation??
