painful pelvic area

Selinaa

Please send help my way! I am experiencing a new pain in my vagina and lower pelvic area. I've had the back pain and the round ligament pain and even the pain of kidney stones and a uti this pain tops all of those. I'm 31 weeks and I have no idea what to do. I also work all weekend and will be on my feet for 8 hours straight with small breaks to sit for one or two mins. Any ideas of what this pain is and what I can do to help it go away I really don't want to miss work and go to the hospital.
