Re: quick question about ortho tri cyclen lo
Seven days means taking a pill a day for seven days, on time, without any interfering substances, without vomitting shortly after swallowing it. After you have taken seven pills perfectly you are as protected as you will ever be on the pill.
There is no way to "check" if the pill is working or not. If you want to, wait for longer then seven days before having sex using only the pill as protection from pregnancy. You don't HAVE to stop using condoms, and if you are unsure of your partner's std status, condoms should be used. However, if you know your partner has no stds, and you have taken the pill perfectly for seven pills in a row, then you are as protected as you will ever be.
