Pelvic pressure/discomfort @ 17weeks....

Kristen • Momma to 3 beautiful girls (2 of which are identical twins). Trying for final pregnancy (hopefully a boy!)
The past couple days I have had some discomfort/ pressure type feeling that is hard to describe down there... I was walking around a lot yesterday and noticed it and now i notice it regardless of what I'm doing. It just makes me nervous because it could be a number of things...
