Pregnancy trimesters are the three stages of the normal 40 weeks pregnancy divided into three months each. These stages of pregnancy are crucial both for the mother and for the child. The mother experiences many physical and emotional changes as she nurtures a new life inside her. Similarly the baby develops gradually in its first home-womb of the mother.
First Trimester Pregnancy

During this stage a woman often experiences morning sickness (vomiting and nausea}, tiredness, tender breast and frequent urination. It is recommended to take small frequent meals to prevent nausea.

Second Trimester Pregnancy
Beginning of the fourth month marks the second pregnancy trimester. At this stage of pregnancy, you may regain your lost energy as morning sickness disappears. You may notice increased vaginal discharge due to hormonal changes in body. Braxton Hicks contractions, which are contractions and relaxation of the uterus, which is often misunderstood as false labor contractions, are experienced. Low back pain and swelling of the feet and ankles may occur. Mild yogic exercises under the supervision of the trainer may help relieve the problem. Kegel exercise i.e. tightening the muscle around the vagina and anus should be done in this stage of pregnancy. This would tone and strengthen the pelvic muscles that take part during the labor contractions. Stretch marks-a great sign of worry for the-to-be moms may be visible.

Braxton Hicks contractions become intense in this stage of pregnancy. You may feel tired and short of breath due to increased growth of the fetus.
Changes In Baby
