Birth control

Soooo I lost a bc pill in my purse an I emptied it out an I found it an with out looking at it just took it and I think it was from a different brand of pack then I found another bc pill an it was to the pack I have now so I took that too ... Is that really bad ? Should I just keep continuing my pack an will it still be effective ? This is stressing me out lol cause I'm not sure if one of them was a water pill cause there 2 different brands !!!! Thanks guys
