text: will i get pregnant after taking my birth control pills? i just finished the 21 day birth control pills and now on my 3rd day off the pills. will i get pregnant if i had sex during the 7 day period off the pills? if you have been taking your birth control pills properly (every day at around the same time) you are protected from pregnancy during your "off" or "sugar" pills. this is also when your period should come. all this information should be included in the information packet you received with the pill pack. as long as you've been on the pills for more than a week (and it looks like you have) you are protected from pregnancy throughout the whole cycle. you are not protected from stis/stds though so if you and your partner haven't been tested you might consider using a condom.  if you are saying "3rd day off the pills" meaning you've decided to not take hormonal birth control any more and stopped before finishing the entire pack, i'm not sure how long you're protected from pregnancy. it doesn't look like you mean that though so you are fine, and should be protected.
