Frequently Asked Questions – Week-by-Week Tracking
Development milestones are based on medical research and represent typical fetal development. However, every baby develops at their own pace, and some variation is completely normal. Always consult your healthcare provider for personalized information.
Every pregnancy is unique. Some women experience all common symptoms, while others may have few or different symptoms. The symptoms listed are common experiences, but your individual pregnancy may vary significantly.
Typically, appointments are monthly until 28 weeks, bi-weekly from 28-36 weeks, then weekly until delivery. Your doctor may recommend a different schedule based on your individual needs and risk factors.
Pregnancy weeks are calculated from the first day of your last menstrual period (LMP), not from conception. This is the standard medical practice, making pregnancy about 40 weeks long, even though conception occurs around week 2.
Due dates may be adjusted based on early ultrasound measurements, which are more accurate than LMP dating. If your due date changes, update the calculator with your new due date for more accurate weekly information.
