If she started taking the pill on the very first day of her period then she would have been covered straight away... however, if she started taking the pill at any other time you should carry on to use condoms for the first 7 days of taking the pill.
If ever she misses a pill, again you should use condoms for the next 7 days after taking it again until it is back in her system.
Read the leaflet that came in the box with the pill so that you can fully understand how the birth control pill works... its isn't magic, it needs to be used correctly for it to be effective ;)
Your lady might be the one taking the pill, but it's important for you to know about it too.

Where ever you got the birth control from, some professionals were suppose to let you know how long it will take before the birth control becomes effective. It's definitely 2 weeks or more from the day she start taking it.
It only takes a minute to falll in love....
I hope you are safe luckily, now a days you can find out quickly.
yes. it takes time for b/c to be effective. if she's ovulating she can get pregnant.
