You have the proliferative phase before the ovulation. After the ovulation you get the secretary phase. Here the glands becomes tortuous. The uterine lining becomes thick. This happens under the influence of both oestrogen and progesterone hormones.
Uterine pregnancy is when a fertilized egg implants and grows in the lining of the uterus. This is the most common type of pregnancy in humans.
It is the design of the nature to prepare the uterine wall for the expected pregnancy. The uterus sheds the wall during the periods. So that the fresh uterine lining can be prepared in next menstrual cycle.
Menstruation is what happens when a woman doesn't get pregnant - after ovulation the uterine lining builds-up in preparation for possible pregnancy, if a woman doesn't get pregnant then menstruation occurs to shed the uterine lining so it can start fresh next cycle. During pregnancy the uterine lining is busy keeping the growing embryo/fetus safe, and women no longer ovulate.
Yes, thickening of the uterine lining is one of the main functions of progesterone during the menstrual cycle, allowing the womb to build-up the uterine lining to support a fertilised egg. If pregnancy doesn't occur then it's the drop in progesterone that causes the uterine lining to break down.
During pregnancy, the placenta secretes hormones that help maintain the uterine lining. These hormones, particularly estrogen and progesterone, support the growth and development of the endometrium to provide a nurturing environment for the growing fetus. If the pregnancy is successful, the placenta continues to produce these hormones throughout gestation to sustain the uterine lining.
Having a period (shedding of the uterine lining) and pregnancy are not compatible but some women experience monthly period type spotting during pregnancy.
During Menstruation. The uterine lining sheds to prepare the uterus for pregnancy. It's due to the drop in estrogen and progesterone.
The uterine lining creates a place for the fertilized egg to attach to in the uterus. Once the egg has attached to the uterine lining, it begins to grow. The lining also helps deliver nutrients to the developing fetus.
Every month the uterine lining is prepared for the pregnancy. Every month it is shed up. Changing of the lining is routine phenomena all over the body. The pregnancy is supposed to be the most precious lining. You can not expect the nature to use the same ling for years together, when the fresh one can be made available easily.
The menstrual cycle is the reproductive cycle.Every cycle a female will ovulate and the uterine lining would plump up in preparation for possible pregnancy. If a woman doesn't get pregnant then the uterine lining sheds (menstruation) in preparation to start a fresh the next cycle.
The menstrual cycle is the reproductive cycle in human beings, and ovulation is one phase of the menstrual cycle. Each cycle a woman will ovulate and the uterine lining plups-up ready for possible pregnancy, but if she doesn't get pregnant then the uterine lining sheds (menstruation).
Some women have light bleeding during their pregnancy but it is not a period, a menstrual period is the shedding of the uterine lining - if the uterine lining sheds during pregnancy the embryo or fetus would be miscarried.
