You had sex before you missed the pills, and you had a couple days that you took pills after you had sex. So, you should be fine.
If you have sex anytime in the next week or so, make sure to use a condom. I know you will be on the placebo pills (I think, from what I gather from your post), and it is the least likely time to get pregnant...if you do, just be safe and use a diff form of protection.
Otherwise, you are fine right now.
