Pregnancy Calculators

Explore our collection of pregnancy calculators designed to support expectant mothers throughout their journey. From due date estimators to fertility windows and weight gain trackers, these tools offer personalized insights based on medical guidelines and individual health data.

Weekly Pregnancy Weight Gain

This calculator estimates the recommended weekly weight gain during pregnancy based on your Body Mass Index (BMI) before pregnancy. It helps monitor healthy weight gain depending on your current pregnancy week, height, and pre-pregnancy weight, supporting optimal health for both mother and baby.

Ultrasound Gestation Period

This calculator estimates the gestational age of a pregnancy based on ultrasound measurements, such as Crown-Rump Length (CRL) or Biparietal Diameter (BPD). Ultrasound-based dating is especially accurate in early pregnancy and helps track fetal development, estimate due dates, and schedule prenatal care.

Safe Days

This safe days calculator helps you identify the infertile period in a woman’s menstrual cycle when the chances of pregnancy are lowest. By entering the date of the last menstrual period, average cycle length, and menstruation duration, it estimates safe days, fertile days, and ovulation. It can be used both for natural birth control and to plan conception.

Pregnancy Gestational Diabetes Diet

This calculator is designed for pregnant women diagnosed with gestational diabetes. It helps calculate important health metrics such as BMI, Ideal and Adjusted Body Weight, Basal Metabolic Rate (BMR), and recommended daily caloric intake. These values help tailor a healthy pregnancy diet and monitor appropriate weight gain to ensure optimal outcomes for both mother and baby.

Pregnancy Due Date

This calculator helps expectant mothers determine their baby’s due date — also known as the Estimated Date of Delivery (EDD). By entering the first day of your last menstrual period (LMP), you’ll get an accurate estimate of your 40-week pregnancy timeline.

Find Your Due Date

This calculator helps you find your estimated due date based on the first day of your last menstrual period (LMP). It also provides key pregnancy milestones, including estimated conception date, fertility window, and the end of the first and second trimesters. A simple and reliable way to track your pregnancy from day one.

How Many Weeks Pregnant Are You?

This calculator helps you determine how many weeks pregnant you are based on the date of your last menstrual period (LMP). It also estimates your due date and shows how many weeks and days remain until delivery. Pregnancy typically lasts between 37 and 42 weeks, and knowing your current gestational age helps track important milestones.

Gestational Age Calculator (AOG)

Gestational age, also known as Age of Gestation (AOG), is the number of weeks a pregnancy has progressed since the first day of the last menstrual period (LMP). This calculator estimates how far along you are in your pregnancy by using your LMP and average cycle length. It’s an essential tool for tracking fetal development and expected due dates.

Fertile Days and Ovulation

This fertility calculator helps women determine their most fertile days and ovulation date to increase the chances of pregnancy. By entering the start date of your last menstrual period and average cycle length, it predicts the optimal window for conception and provides a personalized ovulation calendar.

Date of Conception

Want to know when your baby was conceived? This calculator estimates the date of conception based on the first day of your last menstrual period (LMP) and your average cycle length. It’s a helpful tool for expecting parents who want to understand more about the timeline of their pregnancy.

Crown Rump Length (CRL)

Crown Rump Length (CRL) is the measurement from the top of the fetus’s head (crown) to the bottom of the buttocks (rump), typically taken between 6 to 13 weeks of pregnancy. This calculator estimates fetal length based on gestational age or helps assess gestational age based on CRL.

Chinese Baby Gender

The Chinese Baby Gender Calculator is a centuries-old tool based on the Chinese lunar calendar. By using the mother’s age at conception and the month of conception, it predicts whether you’ll have a boy or a girl. Though not scientifically verified, it’s a popular and fun tradition followed by many.

Child Gender by Blood Renewal

Based on a popular theory, this calculator predicts the gender of a baby by comparing the biological “renewal cycles” of blood in both parents. According to the concept, blood in men renews every 4 years and in women every 3 years. The parent whose blood is “newer” at the time of conception is believed to pass on their gender to the child. While not scientifically proven, this method is widely used as a fun way to guess a baby’s gender.

Child Gender by Rh Factor of Parents

This calculator predicts the possible gender of a child based on the Rh factor (positive or negative) of both parents. Although this method is not scientifically proven, it is based on common folk beliefs that Rh compatibility influences the likelihood of conceiving a boy or a girl. It’s often used for fun or out of curiosity by expectant parents.

Child Gender by Parent Blood Type

This calculator predicts the gender of an unborn child based on the blood types of both parents. Although not scientifically guaranteed, this method is based on popular theories and traditions that associate blood compatibility with gender probability. It can be a fun and curious tool for expectant couples.

Calendar of Ovulation and Fertility

This fertility and ovulation calendar helps you determine the most favorable days for conception based on your menstrual cycle. It predicts ovulation dates, fertile windows, and the next menstrual period, allowing you to plan pregnancy and even estimate the baby’s zodiac sign.
