Every woman, who is planning pregnancy in the nearest future, wants to know when fertilization and implantation occur. It is important to detect the most fertile days for conception, which usually happen in the middle of the menstrual cycle – during ovulation. Another crucial point is the process of implantation. All these phases are the parts of an elaborate scheme, which makes it possible for women to enjoy the motherhood. Every stage lasts for a definite period of time. When you know how and when exactly the mentioned processes take place, you have all chances to get pregnant in the nearest cycle. If this is your main goal, read further.

When Does Fertilization Occur and How Long Does It Last?

Fertilization happens when a mature ovum merges with the sperm cell. Ovulation is an absolutely necessary condition for fertilization. Exactly during this process an ovule enters the Fallopian tubes, where it awaits spermatozoa. This event normally takes place only once in a cycle. This means that fertilization can happen once in 25-35 days likewise, depending on the cycle duration.

Fertilization cannot take place before ovulation. It is a law of nature. After ovulation the ovum stays alive for 12-24 hours only. If it doesn’t get fertilized, you’ll get one more chance to conceive in the next cycle.

“Only 24 Hours for Fertilization?”, You Wonder…

How long does conception take? When does conception occur? Yes, in general you have just 24 hours to conceive, but some preparations for conception start much earlier, approximately 5-7 days before ovulation. Spermatozoa, which have got inside the uterus or Fallopian tubes, can wait for ovulation from several hours up to 7 days! Your vaginal discharge provides them a very favorable environment.

So, even though fertilization happens only during ovulation, don’t exclude the possibility to get pregnant, for example, 5 days before ovulation. How to know whether conception has happened? Actually nobody can predict it. Conception remains one of the greatest life mysteries, it cannot be predicted. It may happen even on the 7th day after sex, in such a case the miracle is starting when you have almost forgotten the details of that passionate night with your partner.

When Can the Earliest Fertilization Occur?

Let’s imagine that sex happens exactly during ovulation or right after it, so the ovum is ready for merging with a sperm cell. How fast do they meet? Well, spermatozoa move as fast as 3-4 mm. per minute. One needs to pass approximately 15 cm. – a way from the uterus entrance to the Fallopian tubes. Under favorable conditions it will take about 50 minutes.

Early Pregnancy Factor

So, fertilization can occur as early as 1 hour or as late as 7 days after sexual intercourse. Certainly, you won’t ever detect any specific fertilization symptoms… too soon, but…wait… Some women truly report astonishing things: they experience unusual sensations, which they can’t even put into words. These symptoms start before the menstruation delay. Have you heard about the biochemical pregnancy stage, when you are already pregnant, but the egg embedment hasn’t taken place yet?

There is a theory, which claims, that you can feel conception practically within 2 hours after sex. In 1974 the information about the so-called early pregnancy factor was presented, though its chemical nature was firstly discussed by scientists 6 years before, in 1968. This term wasn’t clearly explained even 40 years later. By that time a very interesting phenomenon had been already discovered. The fertilized ovum right after its contact with a sperm cell begins to excrete certain proteins with different structures. They help to reorganize woman’s body to the new condition and send the first signs of pregnancy. According to the latest researches such an effect can be caused by chaperonin 10.

Early pregnancy factor can be found in the woman’s blood 24-48 hours after conception. Its level grows during the 1st trimester and disappears completely before delivery.

You may ask when exactly implantation occurs. Let’s see.

How Long After Ovulation Does Implantation Occur?

Sometimes home pregnancy tests show negative results although conception has already occurred. Why does this happen? Taking such premature tests is a common mistake, which the majority of future moms make. The hCG level at this stage is not enough to show a positive result. If you know the terms of fertilization, you will never make such a mistake!

Implantation After Ovulation: Terms and Other Important Facts, When Does Implantation Bleeding Happen?

  • When does implantation occur and what does it feel like? Right after fertilization an ovum, enveloped into a protective membrane, composed of sturdy glycoproteins, starts travelling along the Fallopian tube towards the womb. This trip lasts for 7-12 days, 10 on average. The duration of this process depends on many factors, however, the future embryo needs some nutrition for its development, that’s why it sheds its protective membrane and attaches to the uterine endometrium, using fibers of its inner membrane – trophoblast. In gynecology and obstetrics this process is defined as hatching. Trophoblast’s fibers submerge into the mucous membrane and release certain promoting ferments. Uterine glands alleviate this process, excreting special substances, which make the egg embedment much easier.
  • If embryo’s genetic information doesn’t contain any errors, which mother’s organism reveals, pregnancy develops further. Otherwise, a female organism triggers special protective mechanisms: the womb tries to reject the embryo and menstruation starts. In most cases women don’t even suspect what has happened.

  • The embryo submerges into endometrium slowly, step by step. This process of implantation usually finishes in about 48 hours. Future mothers should avoid any worries, stresses and overworking during this period.
  • Attached embryo begins to produce hormones, responsible for further pregnancy development. Unfortunately, the successful outcome takes place not in all cases. Female chronic inflammatory diseases, uterine anomalies, abortions or other intrauterine interventions impair fertility greatly.
  • During those hours, when embryo is submerging into the uterine wall, women may feel light pulling sensations in the lower abdomen and experience light bleeding. Usually it happens a week or even a few days before period, so it can be mistaken for early menstrual discharge. However, normal menses don’t start. On the contrary, the woman experiences her period delay.
  • Predicting the exact time of embryo attachment is impossible even theoretically. As a rule, fertilization and implantation proceed during 2-3 weeks. Of course, women, who have undergone in vitro fertilization, can count out the terms of implantation more precisely, as they know even the hour when the procedure was implemented.

When to Expect Egg Embedment?

Actually, the egg embedment can take place any time between the 3rd and the 12th day after ovulation. However, early and late implantation cases are not rare. Most frequently the fertilized egg successfully attaches to the uterine wall on the 8-10th DAO. According to the statistics, implantation on the 9th day after ovulation occurs in 37% of women. Other days are less fertile. However, in general 2 ovum cells out of 3 implant during other days within the mentioned time interval. A good idea will be to make your own implantation calendar. Tracking your menstrual cycle can be very useful during pregnancy planning. Use several colors to mark different data in order to avoid confusion.

Why do tests sometimes turn out false negative when implantation has happened? As it was said previously, this happens because the concentration of the hCG hormone in your blood hasn’t reached 25 nmol/l yet. Wait until the 14-15th DAO and take one more test. If your period is delayed by this time, you have all chances to be pregnant.

Why is it so important to know more about the terms of implantation? If you know, even approximately, when the egg embedment has happened, you will definitely pay attention to the way you feel during those special days. Some women report pulling lower abdominal pains, bloody discharge, nausea and mood swings. However, from a medical point of view, you practically can’t feel anything particular at such an early stage. A strong desire to have a baby forces to notice every symptom, even the slightest. Well, may all your dreams come true, especially those ones, which are associated with having a child!
