Forgot to take pill but took it 11 hours later..??

Lita
So I forgot to take my pill last night. I usually take it between 8-10 (usually 9pm) I woke up this morning and realised I took it out of the pack but got distracted and didn't take it. I woke up and panicked and took it at 7:30am. 
My doctor said a while back you're still safe for another 12 hours after missing it. But because I took it this morning.. do I continue taking it tonight? Is it even possible to have two pills in one day but about 13-14 hours apart? 
Someone who actually knows please answer x
