17 weeks, and all is well. I feel much better this week – a little bit like my old self. We went hiking over the weekend, and I’ve been doing low-key exercise regularly without needing to puke. It’s great.

Your baby’s skeleton is changing from soft cartilage to bone, and the umbilical cord — her lifeline to the placenta — is growing stronger and thicker. Your baby weighs 5 ounces now (about as much as a turnip), and she’s around 5 inches long from head to bottom. She can move her joints, and her sweat glands are starting to develop.

5 ounces and 5 inches! Crazy.

I went to prenatal water aerobics last night. It was good, not great. It wasn’t exactly strenuous, but as I become bigger, I’m sure it’ll become more difficult. The best part was meeting some other pregnant women.

There was a class of extremely obese people, mostly women, before mine. I find it disturbing to see people that sick. I just feel sorry for them. Basically, the class is at a hospital, so people there have something wrong with them, pregnancy being what’s “wrong” with me.
