You guys please help me out! I'll be 36weeks on thursday.

So I had horrible diarrhea this morning. Then it happened! My lower back if freaking killing me!!!! Lying down on either left or right side make it so much worse! If I'm standing or sitting it's not so bad. I feel it right in my tail bone and if I turn over while lying down its there and in my hips. It's giving me pelvic menstral like cramps just from resting. I cried turning over from my right side to my left. It's making it so much harder to get out of bed. Oh man... please tell me I'm not the only one? I have an appt tomorrow at 2pm so I'll def bring it up.

Update, my upper ribs in back feel sore now and I'm getting a tone of pressure. Maybe I need to poop again. :( I'm so miserable.
