Your baby is growing at an amazing rate and looking more like a human every day. Continuing the march towards normal proportions, baby's legs now out measure the arms. And, finally, all four limbs have functional joints. Your fetus is squirming and wiggling like crazy down in the womb, though you probably still can't feel the movements. If you have an ultrasound at this point, you might be able to see your baby sucking its thumb!
Your gums may be red and swollen (thanks, hormones), so it's extra-important to take good care of your mouth right now. Brush often, floss gently, and see your dentist if you haven't already. Also, your now-cramped chest and abdomen (baby's growing fast!) might be making you a little short of breath.
My gums are fine, but I am definitely starting to notice some shortness of breath! Having a great time in the 2nd trimester and loving this Spring weather, thank goodness my allergies haven't been too bad yet, going to get some advice on some medication next week fro the doctor in case they get bad.
