Certain hormones during pregnancy will inform the body that conception has occurred and the pregnancy must be maintained. Each of those hormones have their own function and effect (sometimes discomforts during pregnancy) to you. Some of important hormones that produced in pregnancy are: 

HUMAN CHORIONIC CONADOTPOPIN (HCG) 

This hormone is produced during pregnancy only in event of a pregnancy.HCG prevents the release of eggs from the ovaries and stimulates the production of the hormones oestrogen and progesterone.            The HCG level in your plasma and urine in also increase dramatically during the first trimester, but production diminishes once the placenta is mature enough. Unfortunately, HCG contributes to the nausea and vomiting that you often experience during pregnancy. 

HUMAN PLACENTAL LACTOGEN (HPL) 

This hormone is produced by the placenta and ensures proper foetal development. HPL also stimulates the milk glands in the breasts in anticipation of breastfeeding. 

ESTROGEN 

This hormone causes the tenderness and enlarged feeling you experience in your breasts during the early part of pregnancy. Estrogen also prepares the uterus and breasts.You might heard of this hormone before. 

OXYTOCIN

Oxytocin is responsible for the reproductive behaviour in both men and women, and apparently triggers ’caring’ behaviour. It is also the hormone that allows contractions of the womb during pregnancy and labour.
