I think you have nothing to be afraid of. You have really done this right. You didn't use one, but acctually three birth control methods: pills, condom and day-after pill. I guess in your shoes I wouldn't have even taken the day after pill, but it's good that you are careful. The problem with day after pills is that they have a lot of hormones so the pill might mix up your hormonal balance and the period cycle. But if you read the instructions that when to take a next birth control pill, you should be ok.
And about birth control pills. Usually there is 12hours time to take the pill (but read birth control pill instructions). For example if you take one birth control pill at 7 in the morning, the next day you should take it about at 7 am as well. BUT you still have 12 hours. So if u take the next pill for example at 9 am, it's perfectly ok. It's even ok to take it at 6pm. You shouldn't get pregnant by eating pills like this as long as you don't do this every day. So on third day you should still take the pill at 7 am to be on track. So it's ok to take the pill 10 hours late as long as it's not over 12 hours.
I hope this helps. Don't worry too much and if you do, buy a pregnancy test to be sure. All the best to you! :)
