Yesterday I began having pain across my stomach that was pretty uncomfortable but seemed like perhaps stretching. I made note of it but tried to ignore it. The pain then went away. A few hours later I went to stand up and had the most intense back pain on just my right side- to the point I couldn't catch my breath as I was walking. My right side tightened up and the pain wrapped around the right side (as if along the side of my stomach) from navel down to my thigh and through that edge of my back. I tried to use the bathroom but the pain was so intense that I couldn't. It scared the shit out of me but I sat down and started drinking. The pain went on for 10 minutes and then seemed to stop. My mom and I sat talking for 20 minutes or so and I thought it was gone but as soon as I got up the pain was back and as I walked to the bathroom again it had me doubled over. Same pain trying to urinate. I waited again and had the same thing happen again later.
Long story short I suppose this is where I'm looking for advice. I've never been pregnant so I don't know if this sounds like RLP but I called the dr on call (who isn't my dr) and he said it sounds like RLP. I asked if it's normal with RLP to have back pain while urinating that prevents you from going. He said the uterus can put pressure on the bladder and that was the end of that. But even now it's an ache that starts out sharp and continues into a dull pain that gets better after laying on my left side for a while-lying on the right side makes it worse.
Is this something that merits a phone call to my own OB? If the pain had gone away I would probably agree with the dr and just leave it alone, but I woke up tonight to try to go to the bathroom and had pain again. For those who have experienced RLP, do you remember symptoms like I've described? When I google RLP it doesn't sound like this to me.

*for whatever it's worth, I was in on Friday and had protein in my urine but the nurse said it could be from not drinking enough and I didn't think to ask OB...
Eta: And to make the stress worse, I have had pink spotting now this morning. So perhaps that call is in order either way now...
Re: STM: does this remind you of right side round pain (ETA pink spotting)
I would try and get in to see your Dr. If nothing else than for a little piece of mind over the holidays. Better now than a trip to the ER Xmas morning.
Good luck and hope it isn't anything to worry about.
Not saying at all that this is what's going on, but maybe a possibility? I agree call your OB if you haven't already. Hope you get it figured out!
