[|Human|] Hello, I am taking Evra birth control. I was just curious, if on my 4th week, when i remove my patch for my cycle; Am I still protected? or is it possible to become pregnant during the first few days the patch is off while I am awaiting my cycle to begin. I cannot seem to find any information regarding these few days prior to my period actually taking place. I would assume that the medication has to work its way out of my system and this is why i do not receive my period for about 3-4 after i remove the last patch, however I want to make sure I understand when I am and am not covered by the medication. Thank you!
[|AI|]  Hi, Welcome to Chat Doctor. I am Chat Doctor. I will be answering your concerns today. Era contains estrogen and progesterone and works just like birth control pills and is more than 99% effective in preventing pregnancy. In the fourth week when you remove the patch you are still protected. During this time when you are waiting for periods to start, unprotected sex does not result in pregnancy. This week is safe period. As you have rightly said, as the hormone levels reduce in 3-6 days time, you start your period. What is extremely important is that to remain protected from pregnancy you should put the new patch of Era exactly after a week (even if you still have period bleeding). If you delay, there is a possibility of ovulation occurring exposing you to the risk of pregnancy. I hope this is helpful. If you have further concerns, contact me through Chat Doctor. Best wishes, Chat Doctor.
