What to expect during your third trimester:
Your body is still changing. Your baby is getting bigger, so issues you have already experienced are worse.
Backache
You have gained weight in your front, which is putting pressure on your back. Your hips might also hurt. There are a few ways to help:
- Sit up straight and use chairs with back support.
- Sleep on your side with a pillow between your legs.
Bleeding
Spotting could mean there are problems. Call your doctor if you notice any bleeding.
Braxton Hicks contractions
These are contractions that happen before you are in labor. They will be less painful, and happen less often, than real contractions. If you are not yet 37 weeks pregnant and you are having four or more contractions per hour, call your doctor.
Breast size.
By this point in your pregnancy, your breasts might have grown by as much as 2 pounds. There also might be a yellowish fluid coming out, which is normal and will be good for your baby.
Fatigue
By this point in your pregnancy you will be tired from carrying around the weight and waking up at night to go to the bathroom. Nap when you can and eat healthy food for extra energy.
Shortness of breath.
Some women have a harder time catching their breath when they are pregnant. When walking, slow down and rest a few moments.
