So I am taking the oral combined bc pills and I recently discovered that 2or 3 of my pills foil packaging has broken so they have been exposed to air for most likely several days. They have not been wet or damaged, they look normal (I kept them in my purse) and they not exposed to heat as it is winter.
Will they still work effectively?
I have already taken 2 of the exposed ones in a row as they were what i was up to and now I'm worried I am not prtoected.
Are they still effective?

Thankyou
