Some of the physical symptoms you may experience during this period include shortness of breath, hemorrhoids, urinary incontinence, varicose veins and sleeping problems. Many of these symptoms arise from the increase in the size of your uterus, which expands from approximately 2 ounces before pregnancy to 2.

Second Trimester 14 to 26 Weeks The second trimester of pregnancy is often called the "golden period" because many of the unpleasant effects of early pregnancy disappear. During this period, your body is going through a major transformation and needs time to adjust to the changes. Pregnancy hormones, extreme fatigue, nausea and vomiting, tender breasts, and the frequent need to pee are common symptoms that make the first trimester the most challenging time for pregnant women. The third trimester is the final stage of pregnancy and can be considered to be the most painful.

During this stage, your baby is getting bigger, which puts more stress on your body that causes aches and discomfort. As your body begins to prepare for labor, a woman may have irregular contractions known as Braxton Hicks. The prenatal care you receive throughout your pregnancy is essential to the health of both you and your baby, and can improve the likelihood of a safe and healthy delivery.

Knowing what to expect the day of delivery helps, so make sure to take some prenatal classes to get you better prepared for your bundle of joy. The third trimester is considered to be the longest trimester of pregnancy. This trimester begins in week 28 of pregnancy and lasts until you give birth. Most women begin labor around week 40 of pregnancy, while some pregnancies may take longer.

If your pregnancy lasts more than 42 weeks, it is called post-term past due. Take a tour of our labor and delivery facilities, or enroll in educational seminars, breastfeeding classes, or prenatal education. We have everything you will need to prepare for your special delivery!
