That's up to the doctor's advice based on the circumstances of the pregnancy.
Trimester simply is a term that refers to dividing the normal 9 month pregnancy into three 3-month segments. So, the first trimester is the first three months of pregnancy; the second trimester is months 4-6; and the third trimester is the final three months. Hope this helps! Dr. B.

Pregnancy is divided into three trimesters.The first trimester is from the first week to the 13th week.The second is from week 14 to 27. The third and final trimester is from week 28 to the end of your pregnancy (about 40 weeks)
First trimester is the beginning when the developing embryo becomes implanted into the endometrial lining of a woman's uterus. Morning sickness can occur in about seventy percent of all pregnant women and typically improves after the first trimester. Months 4 through 6 of the pregnancy are called the second trimester. Most women feel more energized in this period, and begin to seriously put on weight as the symptoms of morning sickness subside and eventually fade away. Final weight gain takes place in the third trimester, which is the most weight gain throughout the pregnancy. The fetus will be growing the most rapidly during this stage, gaining up to 28g per day. The woman's belly will transform in shape as the belly drops due the the fetus turning in a downward position ready for birth.
When someone is 18 weeks pregnant they are in their second trimester. A pregnancy is usually 42 weeks long. The first trimester is the first 13 weeks. The second trimester runs from week 14 to 26. The third and final trimester is weeks 27 to 42.
