High Blood Pressure.... Fluke

Yesterday I went in for a normal check up and my blood pressure was high, this was a first, my blood pressure (BP) is normally pretty low. My doctor took my BP twice then sent me over to the hospital to get everything all checked out. They hooked me up to monitor the baby and make sure everything was good with him. Then it went to get an ultrasound. I got to see this little guy and find out why my ribs are so sore... He is head down with his feet right by my ribs so every time he kicks he kicks my ribs! They hurt to the point that rolling over in the middle of the night is hard to do. Everything checked out and do far everything is good. My BP has gone down and I am praying it doesn't go back up. My Dr thinks it was a fluke or they are catching something (whatever that thing that might be) before it has started. My Dr also sent me home with this 

I get to pee in this for 24 hours then take it back to my dr tomorrow morning. Hopefully my pee checks out or I might be delivering this little guy the first part of June!
