What happens on day 15 28 of the menstrual cycle?
Luteal phase (day 15-28) The egg cell released during the ovulation phase stays in the fallopian tube for 24 hours. If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates. The hormone that causes the uterus to retain its endometrium gets used up by the end of the menstrual cycle.

Implantation: what happens after the egg is fertilized It takes about 6-12 days for the fertilized egg to travel to the uterus and attach to the uterus in a process known as implantation (1,8). The egg is pushed back towards the uterus by the cilia (1). The egg must attach to the uterus to become a viable pregnancy.
What are the four stages of fertilization?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.

If the egg is not fertilized or does not implant, the woman’s body sheds the egg and the endometrium. This shedding causes the bleeding in a woman’s menstrual period. When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in the uterus.
How can I make my implantation successful?
The best advice is common sense: eat healthily, avoid cigarette smoke, exercise gently, and try some relaxation techniques. You don’t need to confine yourself to bed, but you should go easy on yourself, as you’re going through a lot – both physically and emotionally.
