How Pregnancy Test Calculator Works?

Pregnancy Test Calculator

For you to determine the conception date, the calculator will use the gestation period of the baby to give you the time. The problem is, you do not know the exact date of the conception, and we can all agree that it is seldom known. That is why some platforms if not most of them will give you the option of entering the first day of the last menstruation which you are aware of to calculate the range of dates when the conception is likely to have occurred.

Another way to use the calculator (which largely depends on which site you used to calculate) is to input the due date of the baby. The measurement will typically start after 5-6 weeks since your last menstrual period to determine the gestation age of the baby and the possible range of dates when the conception happened.

So, if you plan to have your baby’s birthday at a particular date, you will see the best timing to get pregnant.

Having exact figures of one of the dates means that you can find out the period when you conceived. The assumption done in most of the calculators is that the average cycle takes 28 days. Another hypothesis is that every pregnancy will take around 40 weeks.

To calculate the estimated range of dates when conception occurred, it will use the menstruation date to count three months back, then add a week to get the due date. If you have the estimated time of delivery, that means will go back 38 weeks to give an approximation of the conception date.

Going for this calculator will suit you if you are a mother who is expecting a baby and is interested in knowing the conception date before taking the pregnancy test. You will also find other calculators to give you the due date, ovulation time and when to try getting pregnant. They are useful if you want to know when you are fertile and possible times for pregnancy.

Conception Facts That You Need to Know

If you experience a regular period, you are likely to conceive after the next 11-21 days after the last menstruation period. Since it is hard to figure out the conception date, the estimation will start from the cycle period.

There are special cases such as for the artificially inseminated women who can know the conception’s actual date. Here the calculation of the conception date is based on the estimated due date.

Common knowledge dictates that the due date will come after 40 weeks of gestation after the last menstrual period, but again, it is another estimate towards solving the equation. It does not guarantee that the baby will be born at that particular date, so there is a higher likelihood of the day coming earlier or later.

The only choice left is to know the first day of your last period to an accurate calculation of the estimated due date (EDD). You can then add 266 days since your last ovulation to arrive at the due date. However, as earlier mentioned, babies will not come at that particular date so give a range of 5 days before the date to schedule for an alert.

A straightforward approach is to use the last menstrual period (LMP), but it gets trickier for ladies with who experience irregular periods. Mainly, your cycle’s first day is also your LMP’s opening day. So, if you are asked when you last menstrual happened, that is the date that you should provide.

However, if you asked about when the last menstrual period ended, it means you also need to take note of that when calculating the conception date. Most calculators will ask the first day as opposed to the last one for the estimation with no more information regarding the period.

You can also find out when ovulation happened using an ovulation calculator. Remember that getting the exact date will depend on whether you experience a regular period – 28 days for most women. This brings in another point, those with inconsistent cycles need calculators that consider them too since it affects their EDD.

Other methods to dictate your conception date

An ultrasound can also be used to get an estimate of the conception date. It is conducted from the 8th-20th week of your pregnancy and used to conclude the gestation age of the current pregnancy.

Another way is using the basal temperature methodology to get the luteal phase or the days after ovulation. This period is between when ovulation happened and the last day before the next period.

Other factors that can affect the estimation vary from one individual to another. Even with a regular period, the ovulation cycles can also change. Another thing, sperm life can fall between 3-5 days which is another aspect that affects the time when conception happened.

Taking the assumption that every woman has a regular cycle, other issues such as stress can alter the monthly cycles making it difficult to realize the exact conception date. Medical research also shows that eggs will take 12-24 hours when shedding meaning that the day of conception may be one day off.

The Practicality of The Pregnancy Test Calculator

The usefulness of the calculator depends on the nature of your menstrual cycle. You do not get the actual date that gives you full certainty, but the prediction provides reliable information.

There are situations where different partners were involved, and the woman in question would like to know who the father is. The calculator can solve such a scenario by giving the date for her to have a clue.

Regardless of the knowledge, performing a paternity test is vital and more reliable when determining the actual father of the coming child. It is especially useful if ovulation was not happening at the time.

For an accurate measure of the conception date, it can only be done if the pregnancy was as a result of vitro fertilization or artificial insemination. If you did not conceive using any of the mentioned methods, the calculator would only issue an estimate.

When to Take The Pregnancy Test

What you will read below answers the question on when should consider performing the first analysis and how soon to implement one. When you know the conception date, it becomes easier since you can finally see if it is time to test.

Whether you do it using urine or blood, a test only shows positive if implantation has occurred, which means that the fetus has already attached on the uterine wall and connected to the mother’s circulation system.

Implantation comes after fertilization, and the attachment happens between 6-12 days from ovulation and fertilization. It will take about three days for the blood test to become positive and several days for the urine after a blood test has confirmed.

Performing the Home Urine Test

The best timing to perform this test is in the morning when you visit the bathroom for the first time. The first-morning urine has the highest concentration of hCG pregnancy hormone. A good idea would be not to go to the bathroom at night then do the test when you wake up.

Regardless of what most of the manufacturers dictate on the test package, a urine test will be positive after a week from the day of implantation, when you realized that a period missed.

Getting a positive test varies widely on some variables. Here are some factors that will determine if your home test will be positive when you carry it out.

Ovulation’s exact day

Having a positive test will largely depend on whether implantation has occurred or not and the urine test will only confirm after several days, 4-5 to be precise. We are focusing on the ovulation day since implantation happens if there were ovulation and fertilization of the egg. If you thought of a later date than the actual day of your ovulation, then other stages will be delayed too.

That is why you need to track your ovulation so that counting to the implantation time can be easy.

Implantation timing

Testing for pregnancy means detection of the hCG (human chorionic gonadotropin) in the urine or blood. The presence of the hormone in the urine detects after blood filtration in the kidney. After ovulation and fertilization in the fallopian tube, it takes about a week for the fertilized egg to move to the uterus and attach to the wall. The range of days when implantation will happen is between six days earliest and 12 days latest.

During implantation, the placenta starts to generate the hCG hormone which joins the central bloodstream. The presence of hCG in your blood will take 3-4 days, and the urine will test positive 2-3 days after the blood confirmation.

hCG level in the blood

If you are having a low hCG count in the blood, it means that you need more days for it to show up before conducting another blood test.

hCG level in urine

The concentration level changes as the day progresses and it is also dictated by the amount of fluids intake. A successful urine test can only occur if the urine is highly concentrated.
