I know you don't know this but a woman's pregnancy is determined by the first day of her last period when she hasn't even conceived yet. A woman usually ovulates about two week into her period (sometimes earlier, sometimes later) But say she's normal and two weeks is when fertilization takes place. So when they say she's six weeks pregnant, the fetus is actually only four weeks old. NO heart, no heartbeat, just a clump of cells that are the size of a poppy seed. So when they tell you there's a heartbeat, they're lying to you. If you don't have an early ultrasound, you'll probably first hear your baby's heartbeat at a prenatal care visit between 10 and 16 weeks.

Month 1 (weeks 1 through 4)
Although it’s strange, the first two weeks of pregnancy are a “getting ready” period. Your body slowly releases more hormones and your uterus prepares for a potential pregnancy. At the end of the second week, your ovary releases an egg (ovulation). If sperm meets an egg just after ovulation, the process to pregnancy continues.

Week 3: Fertilization occurs during the third week. A sperm and egg join and create a zygote.
Week 4: The tiny bundle of cells turns into a blastocyst and implants into your uterine lining. The beginning of what will become the placenta forms. A water-tight sac forms around the blastocyst. This is the amniotic sac, and it provides cushioning to a fetus during pregnancy.
By the end of the fourth week, the blastocyst is about 2 millimeters (mm) long — the size of a poppy seed.
