The menstruation period occurs from day 1 to 28 days which is observed with many phases which begins with:

1. Menstrual phase: begins on the day with the shedding of the thickened uterus which releases menstrual from the vagina. This phase lasts from 1-5 days.

2. Proliferative phase: the phase which is marked by the proliferation of the follicles to form ovules. This phase lasts from 5-14 days.

3. Premenstrual phase or luteal phase: is marked with the ovulation or release of ovules in the female reproductive organs from the follicles. This occurs on the 14th day.

d)1. Menstrual phase

b)2. Proliferative phase

c)3. Premenstrual phase

a) 4. Secretory phase

Step-by-step explanation:

There are 4 phases of Menstrual Cycle:

1. Menstruation: The period- the shedding of the uterine lining.Levels of estrogen and progesterone are low.
2. Proliferative phase: After menstruation the uterine lining builds back up again.
3. Premenstrual Phase: It is also known as the luteal phase. It begins after ovulation occurs on day 14 and continues until the 1st day of the period. It lasts from 10 to 14 days, if it is less than 10 days this indicate a fertility problem sometimes reffered to as luteal phase defect. During ovulation ovaries release a single egg from only one of the two ovaries each menstrual cycle. LH triggers the enzyme to break the wall of follicle by releasing the egg. Then it stimulates the follicle to from corpus luteum and produce progesterone.
4. Secretory phase: The uterine lining produces chemicals that will help in early pregnancy or will prepare the lining to breakdown and shed if pregnancy doesn't occur.
