I lost a birth control pill yesterday.?

Ive been on the pill since Aug 2005. I take the Lesina 28 day pills. I always take my pills on time everyday. But yesterday i lost my pill (day 14 pill). So i didnt take a pill yesterday since i didnt have one. I have 1 more week (3rd week) (Sunday-Saturday regular pills), then 4th week is the white pills that arent horomonal. I should get my period on the 28 or 29 of this month. Is missing a that pill going to affect the day that i get my period now? Is it okay that i just continue with my pills?

Call your doctor or pharmasist and ask. Please take other precautions if you are having sex.

You are lucky!
If you have to lose a pill, #14 is just about the best one to lose. It takes 7 days of hormone pills for your ovaries to become inactive (you had that). Missing one pill mid-pack is not likely to result in pregnancy, provided you take all the rest.
It's possible you could have some breakthrough bleeding, but that would be now. Most likely you will get your regular withdrawal bleeding at the same time as always.
If you are really anxious about it, you could take Plan B. However this COULD throw off your bleeding pattern.

As long as you're not sexually active there's nothing to really worry about. You may have some spotting, but that would be it. Just finish off the pack as you normally would (take Sunday's pill today, Monday's tomorrow, and so on).
If you do have sexual intercourse, use backup birth control for the rest of the pack and the 1st week of the next pack. While the chances of pregnancy are slim, why risk it?

As a future precaution, contact your doctor and ask for a sample pack to keep in the event that something like this should happen again. That way you could just take another pill from that pack and not have to worry.
