A Pregnancy Calculator can provide you with an estimated due date. The pregnancy calculator works based on the ultrasound date, the last period date, the IVF transfer date, or the conception date. The average pregnancy period is 40 weeks i.e., 280 days, starting from the first day of the last menstrual period (LMP). The first day of the LMP is considered as the first day of pregnancy, although conception is believed to occur approximately two weeks later.
It is not possible to accurately predict your due date. Only 4% of women give birth on their estimated due date. Therefore, while you can have a general idea of the due date of your baby, it is important to avoid getting fixed on it. Our easy-to-use pregnancy calculator powered by Sprint Medical can help you to find the estimated due date based on two factors.

How Pregnancy Calculator Works
LMP: Since you may not know the exact time of ovulation or conception, most pregnancy calculators will use the first day of your last menstrual cycle (LMP) to estimate the due date. And this is how most doctors calculate the due date at the first appointment.
Conception Date: Most women ovulate around two weeks after their menstrual cycle. Women are also more likely to remember the date of their last period than the date they ovulated. If you know exactly when you conceived, our pregnancy calculator will add 38 weeks to estimate your due date. If you have periods that are longer or shorter than 28 days, this method may be a more accurate way to calculate your due date than using the LMP.
Ultrasound scan: Ultrasound is a medical procedure in which high-frequency sound waves are used to take live pictures from the inside of the body. A pregnancy ultrasound is a test used to examine an unborn baby. It can provide information about the baby’s growth and health and estimate the due date. Ultrasound can provide a more precise due date of other methods like the last period and conception date.
It is important to note that not every pregnant woman will have an early ultrasound at her first prenatal visit or another early screening appointment. Not all women will perform an ultrasound. Mostly, the ultrasound is performed when you have a few issues like a history of miscarriage, previous pregnancy complications, irregular periods, and many others.
Symptoms of Pregnancy
Pregnancy symptoms will not be the same for every woman. Also, some women experience them as early as a few days after conception, while others take a little more time to feel. However, you should not be concerned if you did not experience any of these symptoms. It is entirely possible to be pregnant without feeling any of the symptoms. The following are a few symptoms of pregnancy.
1. Missed Period
If you are expecting a child, you have likely been monitoring your menstrual cycle. Missed periods are often one of the first signs of pregnancy and can indicate that a baby is on the way. However, missed periods are not always indicative of pregnancy. The missed periods can also be caused by stress, excessive physical activity, diet, hormonal imbalances, and other factors that can lead to irregular menstrual cycles.
2. Morning Sickness
Despite its name, you can experience this pregnancy symptom at any time of day. More than 50% of pregnant women experience morning sickness, a condition characterized by nausea and vomiting, as well as a loss of appetite. Nausea can occur within the first two weeks of pregnancy. Approximately half of the pregnant women vomit as a result of nausea. Although it is a common occurrence during pregnancy, it can become a serious issue if the patient becomes dehydrated.
3. Swollen Breast
Breast changes can happen between the 4th and 6th week. You will probably have sore, swollen, and enlarged breasts because of hormonal changes (human chorionic gonadotropin). In some cases, veins within the breasts may become visible. The area surrounding the nipple may become darker in color and expand.
4. Fatigue
Pregnant women often feel more tired at the start of their pregnancy because their body is making more progesterone which helps keep the pregnancy going and makes the breasts produce more milk. Plus, the body is pumping more blood to get nutrients to the fetus. You can start feeling tired as early as a week after you get pregnant.
5. Frequent Urination
If you are feeling like you need to go to the bathroom more than usual around your next period, it could be a sign that you are pregnant. Of course, it is true that your drinking habits can affect how often you go to the bathroom each day. But if you are pregnant, it could be because your body has more blood in it, which means your kidneys have more work to filter out more fluid and get rid of more waste. So, if you’re expecting pregnancy, you can notice that you’re peeing more often than usual.
6. Other Symptoms
- Constipation
- Mood swings
- Headaches and back pain
- Dizziness and fainting
- Light spotting
- Uterine cramping
- Food aversions
Frequently Asked Questions (FAQs)
One of the best ways to check pregnancy at home is a urine test. There is a special chemical strip (to detect Human Chorionic Gonadotropin-HCG) to carry out the urine test which is available in medical stores. HCG is detectable in the urine approximately ten days after conception. This test is simple to use and cost-effective. Please read the test instructions carefully before using them. Pee in a clean bottle or cup. Place one to four drops of your urine on a chemical strip or dip the strip in the urine. Based on the color you get you may be positive or negative for pregnancy.
For women who menstruate on a regular basis (exactly 28 days), this typically means that an HCG test (urine test) can be done as soon as you go without a period. If your mensuration cycle is irregular, it is better to test after 7-12 days of missed periods to lower the chance of getting false results.
