Pain "down there"

Shannon • Mother of 7 wonderful children and baby #8 is due July 2017!
I am 26 weeks and six days pregnant today. Monday evening I started getting sharp pains in my vagina. It only lasts for a few seconds but comes and goes throughout the day. The midwife is having me come in she thinks they might be contractions. Has anyone else experienced this? While I'm at the hospital I'm going to go ahead and do my glucose test as well!
