No, Marvelon can impact the production and flow of your breastmilk. It could pass over to your baby too. There are other contraceptive options out there that are better for breastfeeding mothers.
If you want to use Marvelon after having a baby, you might have to wait a few weeks before it’s safe to use. You’ll need to be checked over by your doctor, especially as the chances of blood clots after having a baby are high.
