St. Valentine's Day WTF

I had to get my levels tested again today. For reference:

Pregnancy One: First bHCG -- 65, Second bHCG -- 118, Third bHCG -- 176.
Pregnancy Two: First bHCG -- 63.6, Second bHCG -- 190 (four days later -- so it was the equivalent of the Third bHCG in pregnancy one).

Pregnancy Three: First bHCG -- slightly under 200, Second bHCG -- 460.

They've told me not to bother coming in until next Thursday when they're going to do an ultrasound in order to determine what the hell I've got in there.
