Mini rant, I guess :/

Brittany • 30, married, one precious daughter.
Well, to start, I'm almost a week late for AF, but all negative HPTs. I know I'm probably not pregnant, but I just wish AF would show up to confirm it!
Now, to the point: I injured my shoulder recently, and I need to get it X-rayed. I can't lift anything and have extremely limited range of motion. It's getting worse and worse, and it's so painful. Of course, I'm anxious to get the X-ray so I can rule out a few things and move on to the MRI, but I can't get the damn X-ray until I know for sure I'm not pregnant! 
I'm holding on to hope (foolishly) that pregnancy is still a possibility, but at the same time, I need my shoulder fixed! I'm completely wrecked.
So, does anyone have any magical words of wisdom that might help with my shoulder? My doctor suggested heating pads, but it isn't doing a ton of good. 
Sincerely,
A Heathen in Pain
