I have only been on birth control for 7 days and I had unprotected sex, do I have a risk of being pregnant?

My bf pulls out right before and i know there's a chance but is it a big chance?I have only been on birth control for 7 days and I had unprotected sex, do I have a risk of being pregnant?
i was on tri-cyclen glo and my bf cummed in me a few times and i never got preg but after 7 days its not enough, get the plan b pill and it will be fine cuz there is birth control inside you and the plan b is alot more but it may affect the cycle of your other pills and your period, talk to the people at planned parenthood which is where im guessing you got it from or your doctor if they do it that way too.I have only been on birth control for 7 days and I had unprotected sex, do I have a risk of being pregnant?
It is very possible as it usually takes more that 7 days for the pill to be fully effective, and even if he pulls out, some sperm get in there so that is really no protection at all. You should use protection for the complete first cycle of pills, and just because you didn't once, don't increase your chances of pregnancy by doing it again. Use protection.
Usually the pill only takes 7 days to start working, but it does vary depending on the type so check the leaflet. If that's the case it's unlikely you are pregnant - if your pill takes longer though then it's quite possible.
you need to be smacked in the head. Get on your knees and pray that you get lucky and are not pregnant. YOu have to be on the pill for a whole cycle before you are protected, and even then it is not 100% effective.
yes you could be pregnant it doesn't matter if he pulls out because their is sperm in the precum.......and you have to be on birth control for a whole month before they are even working correctly....
Yes there is a big chance. Read the directions.
