Can Implantation Bleeding Be Heavy ?  

3 min read

It is unusual for implantation bleeding to be heavy. Heavy bleeding is the type of bleeding that a person would experience on their period. Implantation bleeding is usually a light spotting that caused by the fertilized egg implanting itself into the uterine wall. Spotting or light bleeding is when there are a few drops of blood on your underwear. It is usually not enough blood to require using a panty liner or pad. 

When Does Implantation Bleeding Happen?

Implantation can occur anywhere from 6 to 12 days after ovulation, but it usually happens about 7 days after ovulation. The earliest signs of implantation are usually light pink or brown spotting. It is also possible to experience implantation cramping during this time. 

How Long Does Implantation Bleeding Last?

The bleeding usually lasts for one to three days, but some women experience spotting for up to a week. If you're having any other symptoms including cramping or fatigue, it's best to talk with your doctor before taking any over-the-counter medications or vitamins.

Is Implantation Bleeding A Sign Of Pregnancy?

Implantation bleeding is a sign of pregnancy if the bleeding is in fact due to the fertilized egg implanting into the uterine wall. The best way to determine if you are pregnant is to take an at home pregnancy test as well as schedule a visit with your doctor to have a blood test done for pregnancy. 

Causes Of Vaginal Bleeding

Other causes of bleeding include an ectopic pregnancy, a miscarriage, your menstrual period, or breakthrough bleeding. Bleeding from a miscarriage or your menstrual period tends to be heavier and very noticeable. Breakthrough bleeding tends to not be as heavy for most people.

If you experience vaginal bleeding between two weeks before and two weeks after ovulation, it could be implantation bleeding or something more serious, like an ectopic pregnancy. An ectopic pregnancy occurs when a fertilized egg implants itself outside of your uterus. This location is usually in the fallopian tubes, but can be elsewhere. Because it is impossible to tell if someone is having an ectopic pregnancy without a medical evaluation involving a doctor, it is important to schedule an in person appointment with an Ob Gyn as soon as you think you may be pregnant. The doctor can draw blood, perform a physical exam, and also do an ultrasound to begin to evaluate the cause of bleeding.

Breakthrough bleeding can occur with the use of any hormonal birth control, like birth control pills, a hormonal IUD, a birth control implant, a ring, a patch, or a shot, like Depo-Provera. Out of these birth control methods, breakthrough bleeding is more common with low-dose and ultra-low-dose birth control pills, the implant, which is placed under the skin of the arm, and hormonal intrauterine devices (IUDs).

After IUD placement, women often have spotting in the first couple months after placement, and it should resolve by 6 months. With the birth control implant, the bleeding can continue beyond the first few months.
