What causes breakthrough bleeding?

Having your period while taking your active pills can be alarming. This is called breakthrough bleeding. It’s one of the most common side effects and often is because you took your pill late or missed a pill. Talk to your doctor if you have questions.

A part from this one, there are many different causes of breakthrough bleeding. Let’s explore some of the most common causes.

Your body needs time to adjust to the hormones in the pill

When you start skipping your periods, you may experience breakthrough bleeding as your body needs time to adjust to the presence of new — or more — hormones. Without a week off, there will be a constant presence of hormones that your body will need to adjust to. The spotting may not begin right after you start your new birth control. It is possible to have a few months without bleeding at all, and then experience spotting two to three months later.

A new birth control prescription

Breakthrough bleeding is often experienced when you switch to a new type of hormonal birth control. Thankfully, this is usually nothing to be concerned about as long as the bleeding is light and stops after your body has adjusted to your new type of birth control.

Not only is your body adjusting to the presence of new hormones, but some specific types of birth control can increase your chances of experiencing breakthrough bleeding. For example, types of birth control with a low ratio of estrogen to progesterone are often to blame for breakthrough bleeding. The type of progesterone present in your birth control pill, patch, or ring can also have an impact. This is due to the role progesterone plays, with estrogen growing the lining of the uterus and progesterone helping to maintain and nourish it. Thankfully, these hormones should balance out eventually.

Forgetting to take the pill

Breakthrough bleeding isn’t always about the body getting used to new hormones. Sometimes it comes down to human error.

If you experience unexpected breakthrough bleeding, this could be because you forgot to take your daily pill! Birth control pills need to be taken consistently at the same time every day and it can be easy to forget. If this has happened to you, you’re not alone.

However, it is important that you don’t miss pills in the future. There are many ways to make sure you don’t forget your pills again in the future, such as reminders and apps.

Syncing cycles

You may have heard of the phenomenon of ‘period syncing’, which can happen when your cycle syncs with that of your roommate, colleague or sibling, and may lead to breakthrough bleeding. If you spend a lot of time around someone with a particularly regular cycle, you may experience breakthrough bleeding as your cycle of hormone production attempts to match theirs.

When to worry about breakthrough bleeding?

There are a few causes of breakthrough bleeding that are more serious. For example, if you are also experiencing diarrhea and vomiting, it may be because the pill hasn’t been absorbed properly or certain medications you have taken concurrently have interacted with the pill. Let’s break down some of the more serious causes of breakthrough bleeding. As always, if you feel uncomfortable, consult with a doctor.



Fibroids are small tumours that can develop in your uterus and can be caused by a variety of factors including hormonal changes during menopause or genetics. Fibroids can mess with your menstrual cycle, causing heaving or longer periods and spotting between periods.

While they are usually non-cancerous and don’t cause any complications, it is always recommended that you see your doctor if you believe this to be the cause of your symptoms.

It’s most often experienced by women between the ages of 15 to 24 who are sexually active. A common symptom is unexpected bleeding, both between periods and after sexual intercourse.

PID is not a condition to ignore as it can worsen if not treated and is an example of a time when your breakthrough bleeding should be reported to your doctor. PID can be easily treated with a course of antibiotics.

If you believe you have an STI, it is important that you get tested and receive medical support from a doctor or sexual health clinic as soon as possible.
