Would You Switch OB's?

So this morning at 2 am I shot out of bed in agony.. I'd never felt pain like this in my whole life. After 2 hours of trying to walk it off I finally broke down and drove myself to the ER. I told the nurse what was happening and she legit looks at me and says "well, things are streching dear.. I have to deal with this other patient " and closed the window in my face!! I was so mad I left. I'm calling HR to file a complaint. On my drive home the pain lessened so I think it was a bound muscle or ligament pain. But when I got there my pain level was almost making me vomit it was so bad. Now, my OB is in affiliation with this hospital and this is where I will deliver and where I get all my ultrasounds. I'm so pissed at that hosptial.. what if something was seriously wrong which I'm not sure it isn't as its happened again today!
