Do I have to take my pill at the same time everyday?

Ruby

I'm on a combined pill (Ortho Tri Cyclen) and I take it about the same time each day (from 11 am to around noon or one) but is it important to take them a the exact same time all the time? Because they're have been days I forgot to take them until late in the evening because of school and other times I completley missed and had to take two the next day. It doesn't happen often but I was just curious

Mainly because I've read so many different things about it.
