The developmental stages a human undergoes between fertilization and birth include: zygote, blastocyst, embryo, and fetus. During these stages, the fertilized egg undergoes cell division, implantation into the uterus, organ formation, and growth. By the end of the fetal stage, the developing human is ready for birth.

The chance of fertilization in humans is restricted to only a few days each month due to the short window of time when the egg is viable after ovulation (about 12-24 hours). Sperm can survive in the female reproductive tract for up to 5 days, but their ability to fertilize the egg decreases over time. This timing helps increase the likelihood of fertilization occurring when both the egg and sperm are present.
The Heart starts to develop 17 days after fertilization.
In general, there are 5 to 6 fertile days every month (the day of ovulation and the 5 to 6 days before ovulation). So there are 60 to 72 days a year that a woman has a chance of becoming pregnant.

The chance of becoming pregnant depends largely on where you were in your menstrual cycle. The time you are most likely to become pregnant is half-way through your cycle, which is when you ovulate. For example, if you start your period every 28 days, then half-way though your cycle would be 14 days from the day you start. If you start your period every 32 days, then your highest chance of becoming pregnant would be 16 days from the first day of your period. The ovulation, which is when the ovaries release the egg for fertilization, usually lasts between 2 - 4 days, but can vary from one woman to another.
Usually 14 days after their period.

Implantation typically occurs 6-12 days after fertilization. Once the embryo implants in the uterus, it can then develop and grow into a fetus.
The shortest "month" of the Gregorian calendar has 28 days.
there are either 30 or 30 days in a month depending on which month it is
