Your Baby’s Development at 2 Weeks

While there is no fetal development at this time, it’s coming, and your body is preparing for it. In your ovary, an egg is maturing and getting ready to break free. Meanwhile, the lining of your uterus is growing and getting thicker to accept and nourish a new life.

Why do doctors add 2 weeks on to pregnancy?

If your period is regular and lasts 28 days, and if ovulation generally happens on day 14 of your cycle, then conception probably took place about two weeks after the LMP. For gestational age counting, these two weeks are added to a pregnancy as a simpler method than trying to track from ovulation or fertilization.

Do you count the first two weeks of pregnancy?

The development of pregnancy is counted from the first day of the woman’s last normal menstrual period (LMP), even though the development of the fetus does not begin until conception, which is about two weeks later.

Can you still test negative at 4 weeks?

Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.

Can a pregnancy test be negative at 4 weeks?

The simple answer is yes, you could still be pregnant even with a negative test, depending on when you took it, but there are also other reasons your period could be late. A pregnancy test detects HCG levels in your urine which increase the longer you are pregnant.

Can HCG be detected at 4 weeks?
