The baby is 8 weeks 5 days old (I gained a day!!). It is 2.1 cm long. It's heart is beating 172 bpm. It has a head, body, arm and leg buds. And yes, there is only one. Whee!!!!!!!!!! We got to see it moving and hear the heartbeat. We see the dr. tomorrow for more info, but this is the important stuff. We will post more tomorrow afternoon after our appointment with the dr. Hopefully he will be able to explain some of the happenings of the last week.
