Frequently Asked Questions
How is pregnancy dated?
Pregnancy is typically dated from the first day of your last menstrual period (LMP), not from conception. This means you're considered "pregnant" for about two weeks before conception actually occurs.
When will I feel the baby move?
First-time mothers usually feel fetal movement around 18-20 weeks. Women who have been pregnant before may feel movement as early as 16 weeks.
What are the trimesters?
Pregnancy is divided into three trimesters: 1st (weeks 1-12), 2nd (weeks 13-26), and 3rd (weeks 27-40). Each trimester brings different developmental milestones and changes.
