What happens if i lose a tray of the combined contraceptive pills mid-cycle?

Question

And how do I continue on with a new pack?

Answer 1

I'd recommend that you just wait for your next period and start a new pack of pills then (either Sunday Start or 1st Day Start).

In the mean time, use backup contraception.  And use this as a learning opportunity...always pack an extra pack of pills with you when you go on holiday...just in case!
