Scarleteen

So my girlfriend has been on ortho tri cyclen lo for several years. This month she accidentally mixed up a day taking the pill. She was supposed to be on the last pill for her week 2 pills but she accidentally took the first pill from week 3. Then on the next day (when she was supposed to take the first day of week 3) she took the last day of week 2.

Is this a problem or will it limit effectiveness? She still took a pill every day, just had one mix up between the pills for week two and week 3.

Thanks!

Each week of pills with ortho tricyclen lo has a different amount of hormones, so if she switched around two pills from two different weeks, then it may compromise the effectiveness. But, as long as she continued to take one pill each day, with none missed or late, then it likely won't have a huge impact. Her best bet would be to check with a pharmacist and see what they say.
