Pregnancy Stages

Congratulations on your pregnancy! Although every pregnancy is different, there are three common stages, called trimesters, that women go through during their nine months of pregnancy.

The best way to ensure a healthy pregnancy and healthy baby is to attend regular prenatal visits with a health care provider throughout your entire pregnancy. These visits will include screenings and general health check-ups to monitor your pregnancy and your baby, and will prepare you for the birth of your baby. To find a pregnancy health care provider that delivers at The Mother Baby Center near you, check out our Find a Provider tool.

Keep in mind that The Mother Baby Center does not provide prenatal care. The Mother Baby Center is where you will deliver your baby. If you have questions about your pregnancy and health care during this time, please talk directly with your pregnancy care provider and clinic. 

FIRST TRIMESTER: 0 TO 3 MONTHS

While you may not yet look pregnant, your body is growing a placenta, adding breast tissue, producing amniotic fluid, and increasing blood volume all to create and nurture your baby. Many women experience physical symptoms, such as fatigue, nausea, morning sickness, breast tenderness, frequent urination, and lightheadedness.

SECOND TRIMESTER: 4 TO 6 MONTHS

By your fourth month, you will likely feel less nauseated and your energy levels will return. It is during this time that your pregnancy will likely become more visible to others and you may find that your regular clothes begin to feel uncomfortable. During the second trimester, it's not uncommon to have heartburn, indigestion, and constipation. Other discomforts may include varicose veins, hemorrhoids, breathlessness, and leg cramps.

THIRD TRIMESTER: 7 TO 9 MONTHS

The last three months of pregnancy may bring some discomfort as your baby continues to grow and develop, stretching and moving more to find room in your increasingly cramped uterus. When you begin your third trimester, you will likely see your health care provider every other week until 36 weeks, when you will likely be seen on a weekly basis.
