Do not stop suddenly on your own due to the risk of returning symptoms, bleeding changes and clots.

Common side effects include headache, breast pain, nausea, spotting, and vaginal itching. Many of these improve as the body adjusts to the hormone. However, get medical help if you notice heavy vaginal bleeding, a breast lump, chest pain, shortness of breath, severe headache, or painful swelling in the leg.
