Implantation Calculator – When Does Implantation Occur? How To Use This Calculator ?
It is simple. And it depends on the way you are trying to conceive – natural or through fertility treatment. If it is a natural way, enter the first day of your last menstrual period and the average cycle length. It would be even better if you know your ovulation date. If you have undergone a fertility treatment, you should pick your embryo transfer date. Once you give these details, you will get the dates, which are important for you to know about conception.>

Implantation is the initial phase of pregnancy when a fertilized egg adheres to the uterine wall. It is most likely to happen around nine days post ovulation but can range from six to 12 days. Here is one such calculator that shows the possible implantation dates based on when you have ovulated or when your last menstrual period was. This is when the pregnancy hormone doubles quickly and lets you know when to take a pregnancy test that comes positive.

When Does Implantation Most Likely To Occur

implantation calculator for pregnancy

Implantation is a critical step in the conception process. It is the time when the embryo adheres to the uterine wall. You may see light spotting or bleeding after implantation and that is one good sign for you to note the time of implantation.

Implantation period is very short, and therefore the sperm needs to be ready to meet the egg. If the sperm is too early or late, it cannot form an embryo.

Ovulation, which is the release of eggs, typically happens around 12 to 14 days after the first day of a period (or the start of a new cycle). Implantation occurs 6 to 12 days post ovulation.

Calculating the ovulation dates, menstrual cycle and implantation can be very confusing. This is where an implantation calculator will help you. This calculator also helps you understand that the bleeding you have spotted is not because of a miscarriage or your next period, but due to implantation.

Most Frequently Asked Questions About Implantation

Q. What are the signs and symptoms of implantation?

In most of the cases, the process of implantation is very gentle. But some women can experience strong signs and symptoms which include:

1. Frequent urge to urinate:

During pregnancy, the hormones are regularly released into the body from the corpus luteum that is located in each ovary. The primary hormone released in the body is progesterone, a steroid hormone required for establishing and maintaining pregnancy. The other hormone is hCG or Human Chorionic Gonadotropin. This hormone comes out from the blastocyst, which turns into an embryo while working its way into the uterine wall. This hormone increases the blood supply to the pelvic region, thereby irritating the bladder and leading to frequent urination.

2. High basal body temperature:

High basal body temperature occurs during a period of prolonged rest, especially during sleep. The best time for you to check the basal temperature is in the morning, just after waking up. If the temperature increases by around one and a half degrees, it could be due to implantation. The rise in temperature occurs between the 7th and 10th day after ovulation. You may also experience a fall in the temperature, called the implantation dip, a week after ovulation.

3. Spotting:

Spotting is the most common sign of implantation. Remember, spotting or bleeding always coincides with the rise in basal body temperature.

4. Swelling, soreness and tenderness of breasts:

The rapid changes in the hormones during implantation make the breasts swollen or sore. These symptoms often occur during menstruation, but recede after a few days. But during implantation, the discomfort can last over a week.

5. Hot flashes:

Hot flashes are not the best indicator as they often occur before or during the menstrual cycle. But at the time of implantation, rapid fluctuation in hormone levels takes place. Therefore, you can experience a hot flash while the embryo is trying to embed itself in the uterine wall. It also releases a significant amount of hCG hormone in the process.

Very few people feel these symptoms during implantation. So do not fret if you don’t experience one or any of these signs or symptoms. Just go ahead and get yourself a pregnancy test done to determine whether you are pregnant or not.

Q. When does implantation bleeding occur?

It occurs around seven to 14 days past ovulation (dpo), when the fertilized egg is implanted in the lining or uterus wall. While it’s happening, a small part of uterine lining can be released or disturbed, resulting in breeding.

Q. What does implantation cramping feel like?

Cramping is also a sign of implantation. Most women tend to confuse implantation cramping with menstrual cramping. But the major difference is that former is milder and lasts longer. The cramping is usually felt in the lower back because of the regular series of contractions that the walls of the womb undergo.

Q. How long does implantation cramping last?

Implantation cramping can last over one or two days.

Q. How common is implantation cramping?

Implantation cramping is quite common at that stage, but varies from one woman to another. There are also chances of it not occurring at all during the process.

Q. Which color is implantation bleeding?

Spotting or bleeding due to implantation is usually pink or brown in color instead of dark red. It’s usually brown in color because, during implantation, the blood takes time to travel from the uterine wall to the vagina, and thus it changes color from red as it is no longer fresh. Implantation bleeding is lesser. At times, the bleeding could be just a single spot, or could go on for several hours or days.

Q. How do you know if it is your period or implantation bleeding?

1. Unlike the bleeding during your menstrual cycle, implantation bleeding is not continuous. It is often spotting or bleeding with intervals.

2. Period bleeding lasts from three to seven days while implantation bleeding can be for one or two days.

3. Whereas cramps are severe during period they are usually mild during implantation.

Q. When can you take a pregnancy test?

The level of hCG hormone has to be more than 25 mlU/ml for the pregnancy to be detected. If the level is lower than this, the pregnancy cannot be detected, even after implantation. Therefore, you must wait at least a week or two after missing the period to take the pregnancy test.

If you experience these signs and have a delayed period, it’s likely that you are pregnant. To get the exact results, take a home pregnancy test. It will give you accurate results. If you get negative results, wait for at least three days before you do the test again.

You can even get a blood test done to see if you are pregnant. Blood tests are more accurate than home pregnancy tests. These tests will give you accurate results as early as 6 days after ovulation.

Remember, the implantation calculator is one of the many ways to determine pregnancy, not the only one. If you have any concerns regarding pregnancy or implantation or if any of these symptoms persist, contact a gynecologist.
