Should I be worried

The past two days I have taken my birthcontrol a few hours late (about three hours after I was supposed to). Other than that I always take it on time. I am just finishing up the first week of a new pack and I've been on it about three months. Last night I had unprotected sex (hence why I didn't take it on time) and I took my pill about two hours after. Should I be worried about pregnancy? This is the first time I've had sex without a condom 😞
