We get asked a lot, “How Long Does Implantation Bleeding Last?”

So let’s first understand what’s implantation bleeding anyway.

Implantation bleeding is not the correct term to describe the egg embedment spotting. It is the term certainly, but for a woman, it may be confusing.

There is no bleeding during implantation that you see as a continuous flow. You only have a few drops of blood coming out of your vagina.

A continuous heavy flow of blood is not implantation. Implantation bleeding cannot continue for long because it is a short & rapid process. A small ball of cells is quickly accommodated by the endometrial lining that is actively growing.

When does implantation start?

Implantation begins after the egg forms a 64 celled blastocyst. After fertilization, the egg goes on dividing and converts into a ball of cells. 

Implantation starts after the blastocyst (guided by the egg membrane) reaches the final site of implantation. The membrane pierces the fibers in the endometrial lining and leads to self-degradation. 

Later the egg starts moving in the endometrial lining creating a space for it. 

After the egg attaches to the endometrial lining, the glands secrete substances that allow the egg to sink in.

Implantation is a 48 hours process, and so at most, implantation bleeding can last two days. Implantation bleeding longer than two days can be because of tubal pregnancy. This is when the implantation occurs inside the fallopian tubes.

Can implantation bleeding last five days?

No under no circumstances can implantation bleeding continue for five days. You are either on your period or have had a very early miscarriage depending on the amount of blood and symptoms.

If you have shortness of breath, chest pain, and intensifying cramps then you may be undergoing a chemical pregnancy which is an early miscarriage.

Implantation itself doesn’t take more than two days; the symptoms will also not last for more than that. It is a rapid process with no risks or after effects. The pregnancy toxicosis is not because of implantation and doesn’t have bleeding as a symptom.

Morning sickness and other early pregnancy symptoms happen after implantation.

Implantation spotting and blastocyst attachment

Implantation is the early embryo attaching to the walls of the uterus. Blastocyst attachment causes the puncturing of the blood vessels and this leads to spotting (bleeding).

Implantation is the process that has to occur after fertilization for successful conception. The color of spotting is brown because the blood does not come out immediately. It takes some time for the few milliliters of blood to come out of the vagina.

Along with implantation spotting, mild cramps also occur. This is because the blastocyst pushes the blood vessels to make space for itself.

After implantation spotting, the blastocyst becomes an embryo and starts developing. The germ layers form, and the placenta precursors start growing. Later on, the organ system formation begins.

Normal and abnormal implantation symptoms

Normal implantation symptoms are not unbearable. Most women don’t even come to know when they had implantation.

Implantation symptoms include mild cramps, spotting, a rise in progesterone and hCG levels, and toxicosis.

The factors produced during the egg embedment makes the pregnant women feel sick. She has vomiting, constipation, dizziness, and weakness. Some may faint due to low energy levels.

Abnormal implantation symptoms include heavy bleeding and cramping. The cramps become very painful and are worse than menstrual cramping. This is because if conditions like Molar pregnancy, chemical pregnancy, and Ectopic pregnancy.

Other abnormal symptoms of implantation include shortness of breath, fever and chest pain.

What symptoms of implantation can be felt?

Cramping during implantation is like tingling and pulling inside the abdomen. Implantation bleeding is a visible sign of egg embedment. The cramps due to implantation don’t last for long. You can only feel these two symptoms of implantation. Other than these the changes due to implantation are internal.
