Name of that hormone is 'Estrogen'. It is called as 'Oestrogen' in British English. It prepares the uterus for pregnancy. It is secreted by the follicles in the ovary.

The Uterus
The hormone progesterone in the corpus luteum will prepare the uterus for pregnancy.
Name of this hormone is estrogen.
The ovaries produce a couple of gonadal hormones. One of these, estrogen, promotes the secondary sex characteristics and sex drive. Another is progesterone which prepares the uterus for pregnancy. Another hormone called in inhibin inhibits the secretion of follicle stimulating hormone.
Every month, the uterus prepares for the possibility of pregnancy, so if nothing happens, the uterus sheds the lining and passes out of the body.
relaxin is believed to help prepare the pubic area and the cervix for the birth
The inside of the uterus is lined with the "endometrium" which is shed every month if you are not pregnant. Once you get pregnant that lining changes to the "decidua" which stays in place because of the hormone progesterone and hCG the pregnancy hormone during pregnancy.
In unfertilized ovum mainly progesterone (high quality) and low quantity of estrogen is released from the corpus leuteum (remaining part of the roptured follicle in ovary. This increased progesterone prepares the uterus for pregnancy. If fertilization occur progesterone estrogen and hCG are released.
The hormone levels are one factor. Estrogen increases contractility of the uterus while progesterone inhibits it. Throughout pregnancy, progesterone levels are high, but just before labor, they fall relative to estrogen levels and contractions start. Another hormone called oxytocin also induces labor. The number of oxytocin receptors increases as pregnancy progresses, and hormone levels rise at labor causing the uterus to contract and begin labor. The uterus also has stretch receptors and will not start contracting unless stretched to a certain degree.
Progesterone is a steroid hormone that prepares a woman's uterus for pregnancy and maintains the pregnancy if one occurs. If conception does not occur, progesterone levels drop which then signals the body to begin another menstrual cycle. It also performs other minor functions such as increasing thyroid function and libido.
