Weighting fetuses is an art, not a science

… or is it “fetii”?

I had another doctor’s appointment this morning. Everything checks out just fine; no effacement or dilation yet. He estimated the baby to weigh about 6 pounds, down from the 6 pounds 12 ounces he thought it was last week. Fetal size estimation is an art, not a science.

I do not have the Strep B bacteria, which is harmless and carried by about 25% of women but can be passed to the baby during birth, so I will not need to have IV antibiotics when I am at the hospital. Yay!

I’ve been having such severe pelvic pain every time I walk or move that I was compelled to do a little research on The Intertubes (doctors surely hate it when their patients “find stuff on the web.”) I read about a disorder called SPD, or symphysis pubis disorder/dysfunction, that describes a lot of the symptoms that I’ve been having: pain when walking, pain when lifting one leg like when putting on pants, inability to stand on one leg, pain getting up from sitting or lying down or getting in and out of the car, pain when rolling over in bed, pubic bone sore to the touch. My doctor said, however, that the particular pain I’m having is a normal part of pregnancy, and many many women experience it.

Not that anything can really be done about SPD anyway; it generally goes away once you’ve given birth and your hormones go back to normal. Relaxin, which is a pregnancy hormone that helps loosen up the pelvic bones, just does its job a little too well in women like me. Thus the pelvic instability and pain.

So I need to just suck it up for the next few weeks and quit complaining about it.

After my appointment, I walked (walked! through the pain!) over to the Baylor maternity ward and filled out a preregistration form. It’s just one form, but it’s that much less paperwork I’ll have to do while I’m in labor.

    What I always found amazing – the way they tell if the baby is head-up or head-down.(Or at least how they used to before the ever present sonogram.) When they grab the part that is up, they move it back and forth (I’m sure they’ve done this on your belly, if not they might soon). If what they grab moves “independently” it’s the head, if it moves the whole body, it’s the butt. Very low-tech. And I like that.

    “Relaxin”? Really? That sounds totally made up. Look, if you aren’t even going to TRY to make this sound believable, there is no way this story is going to get picked up by a publisher.

    Now now, Swompy, this is a science fiction piece. The protagonist is a pod person, with an unknown creature growing inside her. And Relaxin? Totally believable. I mean, it’s about as believable as, say, repeated temporal anomalies and continued use of a clearly malfunctioning holodeck system on Star Trek.

    Carrie: I swear his butt is constantly resting right below my right ribcage. What’s funny is if I poke it he’ll wiggle. Is that mean??! I think his head is down at this point. I feel so much like an overstuffed sausage that I can’t imagine he has any room to flip over in there by now.

    Bender: If you had not been so busy electrocuting yourself with 1940’s era oscilloscopes, maybe you would have done better in the class. You need full use of all ten fingers to effectively juggle.
