So I had a u/s today. I nearly had a panic attack this morning, there was a teeny tiny bit of brown in my cm this morning, but that was enough to have me totally freaked out and worrying that my u/s was just going to show an empty sac. But, thankfully, instead there was a little blob of a baby, with a tiny flicker of a heart beat. Measuring exactly right at 7 weeks, hb 163, I could not have been more relieved. Now to make it to my 12 week appt in March to hear the hb on the doppler, then I can really breathe easy.
