Calculating Your Pregnancy
In case you are just joining the newsletter, this is a reminder of how your pregnancy is calculated. Many people have a challenge trying to figure out when they conceived, how far along they are and when their baby is due. The first day of your last menstrual period is date used for estimating your date of conception, your due date and how far along you are. Pregnancy is tracked from this day even though conception occurs approximately two weeks later. Many people discover that they are pregnant at about the time they miss their period (approximately 4 weeks after the LMP) and get told that they are four weeks along when in your mind you know conception happened about two weeks ago. That is because pregnancy is tracked from the first day of the last menstrual period (LMP).

During ovulation the ovaries release a mature egg that begins to travel to the uterus through the fallopian tubes. Sperm travel through the uterus to fertilize the egg within the fallopian tube. Only a single sperm fertilizes an egg. Both the sperm and the egg contain 23 chromosomes that will combine to make up the zygote which contains a total of 46 chromosomes. At conception, your baby’s gender, eye color, hair color, and much more has already been determined. The zygote continues to travel through the fallopian tubes into the uterus where it will attach itself to the uterine wall.
