2. The pregnancy count

Whenever a woman misses their period, it’s a sign that she is already one month or 4 weeks pregnant. As such the pregnancy calculation starts from the day that she misses her period.

Even when she is examined at the hospital, she is likely to be asked about when she saw her last period. It is often used to determine her expected date of delivery.

3. Changing the breast

Most women experience fullness and discomfort just prior to their menstrual period. During first trimester of pregnancy, the breast becomes fuller, firmer, and tenderer.

The changes in the breast are caused by the female sex hormones estrogen and progesterone produced by the placenta.

These hormones are responsible for the milk sacs of the breast and lead to fat being accumulated around the breast.

Also, the prickly and tenderness frequently felt is simply due to an intensified or enlarged flow of blood through the blood vessels supplied to the breast.
