Anyway, there was good news to be had. F.ranz is measuring on target, and no anatomical abnormalities jumped out. The tech couldn't even find the SCH, but the doctor was able to, though he said it was "tiny" and looked to be going away. He said that this was likely to have no effect on the rest of the pregnancy, though perhaps I still have a slightly elevated risk of something occurring. Additionally, he said it looked like the bleed had been at the edge of the placenta and had NOT lifted up the placenta at all, which is fabulous news.
He said I could exercise but that I should avoid running. That's fine with me. He also said I could schedule another appointment with them in six weeks or so to check the SCH, which of course I plan on doing.
Needless to say, I am VERY relieved. My regular OB appointment is next week. I resolve to enjoy this pregnancy! Until I read a blog where someone has some weird thing happen to her at 24 weeks, and then I'll irrationally worry about that!
