Intense back pain, a couple contractions today not a lot, shocking pains in my vag and bum, and I feel like I have a bowling ball in my vag with hip pressure/pain. Not to mention this morning my under wear was wet (and no discharge color) I felt like I peed 3 times.. 1st very light in color then yellow then a small amount of clear again.. Everytime I stand up I feel the vag pressure... Should I call my hubs and L&D...my liner isn't wet........ Confused on what could be going on.
