When can a woman have implantation bleeding?

The egg after release from ovaries cannot stay for long in the Fallopian tubes. It is viable only for 24 hours. After that, it cannot fertilize as it loses its viability.

Sperms, on the other hand, can tolerate the conditions of tubes and stay in the vagina for about 5 days. If the sperms are present in the tubes during the 24-hour lifespan of the egg after ovulation, then fertilization can occur.

A healthy fertile woman has a fertile window of about five days. The window starts from 3 days before ovulation to one day after it. It is the shortest fertility period and can be longer in some cases. 

For conception, the sperms need to have the right shape, number, and motility. If all these conditions happen simultaneously, then fertilization can occur. 

There is no surety about it, and that is why every time you have sex near ovulation you don’t get pregnant.

  1. After the egg fertilizes, the process of cleavage begins.  It is the rapid division of the fertilized egg into small units. About thirty hours later the fertilized egg divides into two. The next division occurs within 10 hours after it. The third division is after three days after fertilization.
  2. During this cleavage process, the young embryo travels down the tubes. It makes its way to the uterus.
  3. At the end of the fourth day, the embryo reaches the uterus. It has 8-16 units and looks like a mulberry. It is known as the morula stage.
  4. At the next stage, this bunch of cells further divides to form a blastocyst which is of about 64 cells. This solid mass of cells now awaits to attach or implant in the wall of the uterus.
  5. The egg has a protective covering called Zona Pellucida that prevents implantation at the wrong place. It doesn’t expose the sticky ends until the bunch of cells reaches the right place of implantation. Later it gets dissolved. This layer guides the egg to the right place.
  6. After seven days after fertilization, the blastocyst attaches to the uterine epithelium. It leads to a little eruption of the blood vessels present there to make space for the embryo.

After successful implantation, the blastocyst starts the formation of germ layers. These form the different organ systems of the body.

How long does implantation bleeding last? 

The egg lies near the endometrial lining on the 6th day after fertilization and on the 7th day it implants. Implantation bleeding occurs for a few minutes

Even in extreme cases, implantation bleeding cannot last for more than three days. A bunch of 64 cells is too small and is invisible to eyes. Such a small unit cannot cause heavy bleeding.

Implantation bleeding is mostly like spotting and lasts for few minutes or a day. The amount of blood is so less that by the time it reaches out of uterus it becomes brown or dark red. 

A bright red implantation bleeding is a sign that the blood is freshly released.

Signs of normal implantation bleeding

  1. Spotting of pinkish-brown to dark brown color.
  2. Cramps and slight abdominal pain.
  3. Nausea and dizziness
  4. A triphasic pattern of basal body temperature. A rise of BBT on the ovulation day, implantation dip of BBT – which is a sign of pregnancy, restoration of BBT to normal.
  5. Increased cervical mucus due to rising progesterone levels

Some women may have bright red implantation bleeding for a day. But this bleeding will not soak pads.

  • You need to keep a check on the number of pads used.
  • Another point to remember is that you must never insert a tampon into the vagina during implantation bleeding.
  • Do not douche or have sex during implantation bleeding.
  • After you see implantation bleeding get a doctor’s appointment for Rh blood group test. If your baby is Rh positive and you are Rh negative, then opposite blood groups can cause the death of the baby. You will need an immunoglobulin suppressive injection. Earlier a condition called Erythroblastosis fetalis killed many babies. As soon as you see implantation bleeding get a blood group checkup done.

After implantation bleeding, you can take a pregnancy test to confirm pregnancy. You need to wait for the hCG hormone to start coming into your urine. It is like the LH hormone of the brain; it signals the other hormones required for pregnancy.

Implantation also stimulates the production of progesterone. This hormone prevents menstruation and causes the secretion of cervical mucus that forms a mucus plug

This mucus can mix with implantation bleeding and cause orange bleeding.

3) Orangish implantation bleeding

In some cases, due to some infection, the implantation bleeding can be orange. It needs treatment and is a sign of disease. Mixing of cervical mucus also leads to orange implantation bleeding.

4) Pinkish implantation bleeding

Like bright red implantation bleeding pinkish implantation bleeding is also active bleeding. Pinkish spotting later may turn into the brown discharge. The proteins and coagulating factors give a pink color.

What does bright red spotting mean?

Can implantation bleeding have clots?

Pregnancy spotting doesn’t have clots. The vaginal wall doesn’t come off like during the period. The wall stays intact for the incoming embryo and pregnancy development. 

Clots during a period are pieces of the wall of the endometrial lining. Implantation discharge doesn’t have clots.


  1. Hello..mam please reply…I had sex with my wife on April 30…that is her last day of periods.we had an protected sex using condom and also next day eveng before 24 hours she took un wanted pill.after 10ays i.e, on may 10 she started bledding for 8 days upto may 17..and after 33 days,from June 20 to June 26 she had bleeded in brown color.the bledding in these six dasy is very small she pregnant

    • The date of sexual activity is last day of menses. In that case it is not possible to get pregnant normally. The heavy bleeding must be because of unwanted pill. One of the side effects of the pill is heavy bleeding and irregular spotting. You must consult your OB to avoid any future circumstances.
