Pregnancy is typically counted from the first day of your last menstrual period (LMP). Therefore, when you're said to be 2 weeks pregnant, it’s usually based on your LMP. This means the actual conception hasn’t occurred yet; conception typically happens about 2 weeks after your LMP, which is when you’re technically 4 weeks pregnant. This dating method is widely used because the exact time of ovulation and conception is often unknown.
