Should I worry??

So I started the pill on October 23. My boyfriend and I had sex on Oct. 28-30. I read threw the papers with the pill and it said about waiting a full week/7days to be effective as a control. We did go unprotected for the 7 times we did it but as he was getting close to being done, we used a spermicide condom and he finished in that for all the times. If I wasn't on the pill my period would be expected at any time during that time. I'm just wondering if I should be worried about pregnancy.
