Estrogen causes the lining of the uterus to thicken in preparation for receiving a fertilized egg.
Estrogen.
Estrogen levels rise during the first half of the menstrual cycle, leading to the LH surge. This surge triggers ovulation, the release of an egg from the ovary.
Estrogen.
During puberty, increasing estrogen levels promote breast development. During the proliferative phase of the menstrual cycle, estrogen increase causes the bleeding to stop.
Estrogen and progesterone, I think.
An increase in estrogen triggers the development of the endometrial lining in the uterus during the menstrual cycle. This prepares the uterus for a possible pregnancy by thickening the lining to support embryo implantation.
The hormone that regulates the menstrual cycle in women is estrogen. Estrogen is responsible for thickening the lining of the uterus during the first half of the cycle, leading up to ovulation. It also plays a role in the development of secondary sexual characteristics.
Ovaries secrete two kind of hormones: estrogens and progestrogens. The principal estrogen secreted by the ovary is estradiol (regulates the devolpment of external sexual characteristics of females and menstrual cycle). The main progestrogen is progesterone which acts during menstrual cycle and prepares the inner revetment of uterus for pregnancy.

Progesterone and estrogen
There are two hormones that are responsible for the regulation of the menstrual cycle. They are called estrogen and progesterone.
The menstrual cycle involves the interaction of hormones including follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which are secreted by the anterior pituitary, and steroid hormones estrogen and progesterone secreted by the granulosa cells of the ovary.
