I decided to switch brands this month. I consulted the doctor, and he says its fine. However, I don't have enough pills to complete the cycle this month (long story short, i'm missing a week of actives). That means only 2 weeks of active pills on this cycle and then I need to switch to a new one. How should I go about doing this without risking ovulation?
Just start the new pill when the current pack finish. Depending on what types of pills you were on and are going to, you might or might not have to consider yourself fertile for the first 7 days after switching. Your doctor should have told you if the 7 day rule should be followed.
What do you mean start it when the current pack finishes? Technically this pack isn't going to "finish" because it isn't complete. So do you mean go from taking the last pill I have (2 weeks into the cycle) straight into a new pack the next day?
Yes, this: "So do you mean go from taking the last pill I have (2 weeks into the cycle) straight into a new pack the next day?" Skip the inactive pills. So as soon as you take he last active pill from the pack, start the next pack the next day.
