How late is too late?

Madeline
Hey! I'm on a birth control pills that are on a 28 day cycle (21, 7) and I take it everyday at 8 am, no fail. Until these past 2 morning when I've taken it at 9:50 then 10:50. 😟 So my question is, what is the time frame from when you normally take it (for me, 8 am), is it still effective? Was 9:50/10:50 too late?
