You may have less heartburn and have easier time breathing when your baby starts to "drop" down into your pelvis. This process — called lightening — often happens a few weeks before labor if this is your first baby. (If you've given birth before, it probably won't happen before labor starts.) If your baby drops, you may also feel increased pressure in your lower abdomen, which may make walking increasingly uncomfortable, and you'll probably find that you have to urinate even more often than before. If your baby is very low, you may feel lots of vaginal pressure and discomfort as well. Some women say it feels as though they're carrying a bowling ball between their legs!
Feeling absent-minded? Forgetfulness is normal during the last trimester. You may be overwhelmed or just plain distracted by the huge life changes you're about to experience, as well as exhausted if you're having trouble getting a good night's sleep.You might also notice that your Braxton Hicks contractions are more frequent now. Be sure to review the signs of labor with your practitioner and find out when she wants to hear from you. If you're full term, your pregnancy is uncomplicated, and your water hasn't broken, she'll probably have you wait to come in until you've been having contractions that last for about a minute each, coming every five minutes for an hour. Of course, you'll want to call right away if you notice a decrease in your baby's activity or think you're leaking amniotic fluid, or if you have any vaginal bleeding, fever, a severe or persistent headache, constant abdominal pain, or vision changes.
