12 weeks

How your baby's growing: Your baby's hit the 2-inch mark (about the size of a lime) and weighs half an ounce. Her face is beginning to look more human. Her eyes, which started out on the sides of her head, have moved closer together on her face, and her ears are near their final positions on the sides of her head. Your baby's intestines, which have grown so rapidly that they protrude into the umbilical cord, will start to move into her abdominal cavity about now. Her kidneys are secreting urine into her bladder. Her nerve cells have been multiplying rapidly, and synapses (neurological pathways in the brain) are forming. Your baby may have acquired more reflexes by now, including sucking, and she'll even squirm if you prod your abdomen, though you still won't be able to feel her movement for several weeks.

How your life's changing: Your uterus has grown to the point where your healthcare provider can now feel the top of it (the fundus) low in your abdomen, just above your pubic bone. Though you probably won't need maternity clothes for several more weeks yet, you've no doubt noticed that your waist is thickening and that you're more comfortable in looser, less restrictive clothing.

You may also start getting heartburn (also called acid indigestion), a burning sensation that often extends from the bottom of your breastbone to your lower throat. It's caused by both hormonal and physical changes in your body — and can take the pleasure out of eating a meal or sleeping. Eating small meals and avoiding foods that make the problem worse, such as fried, spicy, or fatty foods, can help.

How I'm doing: I finished taking my last dose of antibiotics this morning. I'm pretty much back to 100% now. I still have a little bit of congestion in the morning but nothing too terrible. I think any nausea I had is pretty much completely gone as well. Eating is much easier and I feel better in general. I'm glad it was fairly minor and didn't last long. My energy is slowly returning. I'm definitely still not myself. I don't have much trouble staying up at night but I do have trouble getting up in the morning. I could sleep much later. I got up relatively early this morning (8:30 AM) and only made it until noon before taking a nap.

I purchased a few more maternity items today. Most of my jeans are too tight. A few pairs can be buttoned but they are very uncomfortable after sitting for any length of time. I'm starting to move clothes out of my closet that aren't comfortable to wear any longer.

Tuesday is the big day. It's Grandma Sue's birthday and it's also the day of our first ultrasound. We're very excited to see this little baby and make sure it's doing OK in there. It will also be nice to have confirmation that there's only 1. We'll make sure to post pictures. According to all the books I have it should look like a cute baby in there at this point even though it's only a few inches long.

Less than two weeks until the end of the first trimester.
