Hormonal contraception often changes your bleeding. It may get lighter, become irregular or stop. Here is why, what to expect, and when a change is worth checking.

Why bleeding changes

Hormonal contraception changes the hormones that control your cycle, so your bleeding usually changes too. Many hormonal methods make bleeding lighter and shorter, and they can help with heavy or painful periods. The hormonal IUD can make bleeding lighter, irregular or stop altogether. The injection can cause bleeding between periods or missed periods, and the implant can cause irregular bleeding. The copper IUD contains no hormones, but it can make periods heavier.

Bleeds on the combined pill

With a standard pack of combined pills, you take pills containing hormones for 3 weeks, then have a week without active hormones. The bleeding in that week is called a withdrawal bleed. It is your body's response to the drop in hormones, and it is not the same as a natural period. The patch and ring usually follow a similar pattern, with a bleed in the week off.

Spotting and breakthrough bleeding

Light bleeding or spotting at other times, called breakthrough bleeding, is common in the first few months of the combined pill. It can also happen with the progestogen-only pill, and it is common when hormonal methods are used without a break to skip bleeds. It usually lessens over time as your body adjusts. If spotting still bothers you after about 3 months, talk to a doctor, nurse or pharmacist.

When bleeds stop

Having no bleeds on hormonal contraception is not harmful. Your body does not need these bleeds to stay healthy. If a method is safe for you, using it to have fewer bleeds is usually safe as well, but check with a doctor or nurse first. One thing to know: without regular bleeds, it can be harder to notice a pregnancy. If you have signs such as feeling sick, sore breasts or unusual tiredness, take a pregnancy test.

When to get checked

Logging bleeding and spotting in Ciclo can show whether a new pattern is settling. See a doctor, nurse or sexual-health clinic if you bleed after sex, if bleeding becomes heavy, or if a settled pattern changes for no clear reason. New bleeding can sometimes be caused by an infection such as chlamydia. Get emergency help if you have severe pain low in your tummy, especially on one side, and you could be pregnant, or very heavy bleeding with dizziness or fainting.

This is general information. If your bleeding changes in a way that worries you, talk to a doctor, nurse or pharmacist.
