I would definitely go and get emergency contraception (the morning after pill). If you have only been taking the combination pills for two days, they would not be effective yet anyway and I'm very surprised that your doctor didn't tell you that. Even if you hadn't missed your pill yesterday and today, you would still be at a higher risk of pregnancy.

Go get the morning after pill as soon as possible. It can be expensive, so you might need to get your boyfriend or parents to help pay for it, but it costs a lot less than a baby.
