Okay back to joking then....we dont want you stressing....
 
  
Glad to hear the temp has dropped.  My Rottie girl Dava that I bred, she refused to take her bed when she was pregnant. She jumped a 4 foot fence after a rabbit (got yelled at, scared the CRAP outta me) played for a few minutes waltzed in the house and BAM had those babies! I missed the first 5!  I mean she had just been running and jumping so I thought ohhhh she has a day or 2....She ended up having 13 babies....one lil boy passed so we ended up with 6 girlies and 6 bouncing boys.... 
So you think you hear 3 heart beats or 4??   ohhh I wanna hear the hearts too!!!!
