Pregnancy Milestones

Heartbeat

Baby's heartbeat can typically be detected between 6-8 weeks via ultrasound. The average fetal heart rate is 120-160 beats per minute.

First Movements

Most women feel their baby's first movements (quickening) between 18-22 weeks. First-time mothers may feel them later than experienced mothers.

Taste Development

Around 13-15 weeks, your baby develops taste buds and can taste the amniotic fluid, which is influenced by what you eat.

Eye Opening

Your baby's eyelids open around 28 weeks, and they begin to blink. They can perceive light and may respond to bright lights.

About Pregnancy Calculation

How Pregnancy is Calculated

Pregnancy is typically calculated from the first day of your last menstrual period (LMP), which is about two weeks before conception actually occurs. A full-term pregnancy is about 40 weeks from LMP.

Due Date Accuracy

Only about 5% of babies are born on their exact due date. Most births occur between 37-42 weeks. Your due date is an estimate to help track your pregnancy progress.

Trimesters Explained

Pregnancy is divided into three trimesters: First (weeks 1-13), Second (weeks 14-27), and Third (weeks 28-40). Each trimester has distinct developmental milestones.
