H2: Pregnancy Calculator FAQ

H3: How accurate is a due date calculator?

A due date calculator provides an estimate based on a typical 40-week pregnancy. While many babies are born close to the calculated due date, only a small percentage arrive exactly on that day. Doctors may adjust the due date during pregnancy based on ultrasound measurements and the baby’s development.

H3: When does ovulation usually occur?

Ovulation typically occurs about 14 days before the start of the next menstrual period in a regular cycle. However, every cycle can be slightly different, which means ovulation may happen earlier or later. An ovulation calculator can help estimate the most fertile days in your cycle.

H3: How many weeks does a pregnancy last?

A full pregnancy usually lasts about 40 weeks, counted from the first day of the last menstrual period. Pregnancy is divided into three trimesters, each with important developmental milestones for the baby. Tracking pregnancy weeks helps expecting parents follow their baby’s growth.
