Forgot to take the pill

Cindy
Hi, i just have a quick question, yesterday i was supposed to take my birth control pill Al 7 o'clock in the morning but I forgot, it wasent till today's morning u realized I didn't. I had sex yesterday, he didn't wear a condom but he pulled out in time. My pill had a 12 h tolerance window but I'm 24h late. What do you think I should do? Should I take 2 pills? Do you think I may get pregnant? I'm on my first week taking the pill. Thanks.
