Oh my gosh, they came the same day!
Second beta, 15dp5dt: 2335! Holy cow! That's a doubling time of 38 hours (with 48-72 being the goal for indicating a healthy pregnancy). My IPs are definitely expecting at least one bundle of joy in the next 8 months or so!
There wasn't much data available on the message board for this particular date, as most people are done with their betas before now. But here are my numbers for comparison:
15dp5dtSINGLETON: 84, 150, 726, 849, 1224, 1277, 1356, 1574, 1799, 1965, 2088, 2265, 2335, 3314, 4320
TWINS: 786, 919, 1150, 1586, 1685, 2335, 2400, 2616, 2751, 3022, 3088, 3427, 3903, 3930, 4050, 4744, 7874
It's still possible that it is a singleton, but my numbers are climbing to the top of the list, and also moving up toward the middle of the twin list. So, the signs are starting to point more toward double trouble!
My progesterone level is still great, at 39. So I'm supposed to stay on all the same meds.
Next step, our first ultrasound! I am supposed to schedule it for anytime starting next Thursday, Jan. 3, which will be 5 weeks, 6 days pregnant. I think I am going to schedule it for sometime the second week of January, closer to 6.5-7 weeks so we are sure to see the heartbeat(s). My IPs will be coming from Chicago to get the first peek at their little one(s), so I want to make sure they get a good show!
