One week pregnant. Signs, symptoms, and what to expect. In this video, we will discuss.
Most women don't realize they're pregnant during the first or even the second week, and it's completely normal.
Are you even pregnant in week one?
Technically, in week one, you're not yet pregnant.
This week begins on the first day of your last menstrual period.
The conception hasn't happened yet.
Doctors calculate your pregnancy from the first day of your last period, not from the day of conception.
That's why week one is part of your pregnancy timeline.

Baby's development week one
During week one, the egg begins its journey from the ovary into the fallopian tube.
So, your baby hasn't formed yet.
The future baby is called a blastocyst at this stage.
It will later split, the outer part forming the placenta, and the inner part forming the embryo.
Baby size in week one
There's no baby size yet because you're only technically pregnant.
But don't worry, exciting changes are just around the corner.
Is ultrasound done now?
No ultrasound is done in week one unless you're undergoing fertility treatments,
where scans help check for follicles and fibroids.
What should you eat?
Include foods high in 1. Folate, example, leafy greens, legumes
2. Calcium, example, dairy, broccoli 3. Iron and fiber, example, whole grains, berries
