I have been having back pains for the last 2 days. Today i really noticed that I got kicked in the back. First time since being pregnant with the twins.. I am 35 weeks and 3 days. When i go to the bathroom. Which has only been to pee. My panties are clean but then when I wipe. Its yellow and brown on it. I am very clean and have taken a shower. Plus i haven't pooped so its not that. What could it be? Any ideas. I'm trying to hold out. Until the morning but not sure if I can. My feet are swollen and hurting. My hands are not really swollen but they hurt. My blood pressure is 114/76.
