WittyUsernameHere answered Tuesday June 8 2010, 5:15 pm: There are two general types of birth control pills.
The first has progestin, the second has progrestin and synthetic estrogen. All you really need to know about that is that progestin only pills are rare, and that progestin only pills become ineffective relatively easily while the estrogen/progestin mix type pills can miss a full day, double up the next, and only drop from 99 to 97 or 96 percent effectiveness.
The pack will probably say, or you can call your gyno and ask, but 99% chance they gave you the combo pills and you're more than fine. An hour or two's variance on those makes no difference. [ WittyUsernameHere's advice column | Ask WittyUsernameHere A Question ]
