Ultrasound and a crap day

I went for the horrid internal ultrasound today, the technician was really lovely and chatted with me in an easy friendly way. It was uncomfortable and unpleasant but I made it! 

However, the ultrasound showed nothing at all, my recent bloodwork is fine and nothing at all is showing up as abnormal. 

I've spent one week with revolting cramps coming every ten minutes as well as some 'other' symptoms. 

This is very confusing, I'm awaiting a call from my gp now and hope that we can find out what the hell is going on! 

When I got home my bedroom door had been accidentally locked and so I couldn't get in to keep working on my thesis, total fail day!!
