The pain started at 6 am after I was up all night peeing every 30 minutes seemed like. It started on my left side right in the middle of my side then progressed to my right side in the same spot, right in the middle, then eventually stretched all the way across my lower back. It felt like i was having contractions in my back.. and a small amount of cramping. I then got up to take a bath around 7:30 to try and ease the pain and had a gush of yellow/greenish thick discharge. About an hour after my bath the pain stopped.. any idea??
