Hi friends! I have a quick question for you. My doctor switched me recently from Alesse to Tricyclen. I just finished my Alesse pack today (so 28 pills) and would have started my new pack tomorrow. This time I filled my prescription so I have a pack of Tricyclen instead, which I assume I have to start tomorrow as I would have started the Alesse. Do I need to use extra protection for 7 days or is my Alesse going to "carry over"? From what I understand Tricyclen goes in increasing doses every week so I don't know if that makes a difference. Thanks for your help!
