I'm on birth control pills and i take them regularly if i had sex a week ago and i got my period this week should i worry about being pregnant ?

Probably not: If this period is on schedule then there is little to worry about. If this bleeding was not expected then you need to be more cautious.

No : Regularly taking the pill, same time every day and not missing any - especially the start of a new pack on time is 99% effective in preventing pregnancy. Higher failure rates are associated with inconsistent use. Plus you got a ? Normal menses and you had sex at a less fertile time frame - all adds up to very low risk of pregnancy.

Don't worry, b happy: You didn't mention if your period this week was on schedule as expected. If so, your period is usually a good indicator that you're not pregnant and your pills are doing their job.
