Hello, You are right, Linessa contains two hormones, and one of them varies in concentration during the first 21 days. That said, this variation does not affect the ability of the pill to be taken continuously. Indeed, in the case of a pill like Linessa, it is necessary to omit taking the last 7 pills (the white pills) and simply start a new pack. I recommend that you discuss with your pharmacist to inform him of your desire to take the pill continuously. He will then be able to recommend you well when you have questions about the effectiveness of your pill (for example, if you forget a pill). Does this answer your question?
