"I have been taking Aviane 21 continuously for 2 months. For a week and a half, I have been experiencing heavy spotting similar to menstruation. Is this normal?"

Yes, it is normal to experience spotting while taking Aviane 21 continuously for 2 months. Spotting is vaginal bleeding that occurs outside of your regular menstrual period. It is usually lighter and can be a darker color. This can happen for up to 3 cycles (or 3 months) as your body adjusts to the hormones in the pill. It is recommended to take a break of 3-4 days between each pack of pills to help your body adjust. As long as you do not stop taking the pill for more than 7 days in a row and do not miss any pills, the effectiveness of the birth control should not be affected.
