Implantation bleeding: what is it, main symptoms!

Implantation bleeding happens when the 6-12 day old fertilized egg attaches to the inner lining of the uterus , something known as implantation can occur. This movement of the egg can result in light bleeding or spotting, which is completely normal and does not require any medical attention.

Overall, about a third of pregnant women experience this. While similar in timing to a woman’s menstrual period , the two should not be confused as there are differences.

What is implantation bleeding:

After ovulation and the moment an egg is successfully fertilized by a sperm, the embryo begins to divide and grow, sending signals to a woman’s body to prepare for pregnancy . In turn, the walls of the uterus , called the endometrium, begin to change: they have already become thicker over the course of the menstrual cycle , but will need to grow and mature further to protect and nourish an embryo for nine months.

Anywhere from six to 12 days after fertilization, the rapidly growing embryo has traveled down the fallopian tubes into the uterus . It’s starting to need more nutrients, and the endometrium has filled up enough to support the embryo. Also, at this time, the embryo attaches to the endometrium, where it becomes dependent on a mother’s body for the first time for nutrients and oxygen. Implantation bleeding happens when the embryo enters the uterus , which sometimes causes small blood vessels to rupture.

Symptoms of implantation bleeding:

Every pregnancy is different, as are implantation bleeding symptoms . They can also differ from the first pregnancy to subsequent ones. Some women do not notice any symptoms associated with bleeding .

1. Small bleeding:

It is one of the main symptoms of implantation bleeding and probably an accurate sign of pregnancy. This happens when the embryo attaches itself to the wall of the uterus . So, if you notice light bleeding or spotting before your period starts, you don’t have to worry.

2. Implantation of cramps:

The second common symptom after implantation bleeding is detected is implantation cramping, which is similar to menstrual cramps. However, these cramps are milder and less painful. So where does implantation cramp occur? You will experience them on your back and lower abdomen and last for a few days.

They are sometimes associated with continuous contractions in the uterine wall. If the cramp is severe and unbearable for a long time, it is advisable to consult your doctor.

3. Breast changes:

Right after implantation bleeding , your body starts to change. The breasts undergo changes such as tenderness, pain and swelling . It is due to the change in female hormone levels after conception. In some cases, these changes are visible during ovulation as well as a week after ovulation .

4. Increase in basal body temperature:

Basal body temperature (TBB) is high during implantation and may be a way to determine pregnancy . You may not necessarily track your body temperature unless you are trying to conceive. Therefore, you should map your daily temperature and see if it is increasing. TBB rises at the time of ovulation  due to the increase in the hormone progesterone and remains elevated when implantation occurs.

5. Frequent urination:

The urge to urinate increases within a week of implantation bleeding . Your body undergoes major changes to make room for the baby. Increased blood supply  to the pelvic area puts pressure on the bladder. This pressure increases your urge to urinate.

6. Food cravings/aversion:

This is another prominent sign of implantation bleeding . The hormones produced as a result of implantation tend to alter a woman’s likes and dislikes for food. You may crave foods you haven’t tasted before or dislike foods you’ve loved. However, any craving or aversion for food within seven days of ovulation  cannot be considered an implantation symptom.

7. Heat waves:

They are less common signs of implantation bleeding and last about 15 minutes at the time of implantation. During implantation, hormone levels fluctuate rapidly, causing hot flashes. Although it is an inconsistent sign, you can still consider it in association with the other symptoms.

8. Muco Cervical

An increase in progesterone levels after implantation causes the cervix to swell  and increase blood flow to it. In addition, the glands enlarge and hormones stimulate the glands to produce more cervical mucus. The mucus thus contains some blood , which is why cervical mucus after implantation bleeding appears pinkish or brownish in color. While the above signs can determine your pregnancy , you can’t be sure until you get tested. Also, remember that not every woman has these signs.

How long does implantation bleeding last?

Implantation bleeding should not exceed 3 days and should not flow. If so, something could be wrong. In these cases there is the possibility of low hormone ( progesterone ) which would pose an imminent risk to the recent pregnancy and in this case you need help from a gynecologist.

There are risks of implantation bleeding:

Implantation bleeding  should not be a cause for concern and should not pose a real risk to the developing baby. If you have bleeding or spotting more than a few days after your period , there is likely no implantation bleeding. Real pregnancy concerns rarely come from implantation bleeding  and usually occur after your missed period. Although this slight post-implantation bleeding during pregnancy is not considered normal, there are a few main reasons it can occur:

  • Irritation of the cervix  (especially after OBGYN exams)
  • Irritation or small tears from sexual intercourse;
  • Heavy or excessive lifting or exercise/exertion;
  • Vaginal infection.

At least 50% of women who experience spotting bleeding (in addition to implantation bleeding) will have a normal, healthy pregnancy . Prolonged bleeding can be a sign of something more serious, especially during pregnancy . Molar pregnancy or miscarriage are two concerns, which is why whenever you visit your doctor, you need to let them know about current or recent bleeding (especially if it’s heavy) as well as any other symptoms.
