Are you pregnant this week?

You wouldn't actually be pregnant, but if you conceive this week, then you'll be two weeks pregnant. That's because healthcare providers use your last Menstrual period to determine your due date, so technically the first day of your period is also the first day of your pregnancy. As you ovulate for about two weeks into your cycle, conception happens during the time you're two weeks pregnant.

Which is the best time to conceive

You would be most fertile during the three days which leads up to ovulation. There are signs which appears while ovulating such as basal body temperature, breast tenderness, mild cramps and increased vaginally discharge.

Fertilization

When sperm meets egg

At the 24 hours after ovulation, your egg could be fertilized if one healthy sperm manages to swim from your vagina through your cervix, then through your uterus into your fallopian tube and then penetrate the egg. There are closely 250 million spem in an ejaculation and 400 sperm survives the 10 hour long journey to the egg. But it's usually only one that succeeds in burrowing through its out membrane.

The genes combine

In the next 10 to 30 hours, the successful sperm's nucleus merges with the egg's and they combine their genetic material. When the sperm carries a Y chromosome your baby will be a boy. And when it's an X chromosome, you'll conceive a girl. The fertilized egg is known as a zygote.

Implantation

The egg would take three to four days to travel from the fallopian tube to your uterus, where divides into 100 or more identical cells along the way. As it enters the uterus, it's called as the blastocyst. A day or two later, it starts burrowing into the lush lining of your uterus where it grows and divide.
