Waiting for that Heartbeat!

Molly
I'm right at 5 weeks and have set up an appointment for 7 weeks 3 days to hear a heartbeat and the waiting is killing me!
At 4 weeks 6 days my hcg was at 3,200 but progesterone was low so I now have the little capsules to take twice a day. I'm stoked my hcg was high but progesterone stress has officially kicked in! 
Every few hours I check to see if my boobs are still sore. Some days I pee every 30 minutes and some days I pee every few hours. The more I analyze my symptoms the more scared I get. 
Anyone else in that horrible waiting period?! What do you do to combat it?
