Yes, it is normal for your period to start before the removal of the contraceptive patch. This can happen when you first start using the patch and may continue for the first few months. If the spotting persists after 3 months, it would be best to consult with your doctor. If you are breastfeeding, it's important to know that the contraceptive patch can affect milk production. If you are not breastfeeding and have had unprotected sex during the first week of using the patch or before, it's recommended to take a pregnancy test.
