Birth Control but no condom?

Hi everyone. I have been on the birth control pill for about 3 or so years. I was first on tri-sprintec but switched to sprintec about 1.5 to 2 years ago. I have never had an issue on either of these, but especially on sprintec. I have an alarm set so I take my pill every morning at the same time and have NEVER missed a pill on the 3 years I've been on it. My boyfriend of a year and I have been very sexually active lately and we don't always use condoms because we are both clean of STD's and I have always trusted him AND the pill. However, I just got my period this past Wednesday. That means that today (Sunday) I started the first pill of a new pack for this month and I still had my period; it was beginning to end soon. My boyfriend and I had sex today, he said he pulled out all the way but he was very close to me. Since I've never had an issue and have been on the pill for so long I'm pretty positive I'm absolutely NOT pregnant, but I just wanted some comments and advice so I don't spend the next 4 weeks worrying about getting my period. So in summary, I've been 110% consistent on the pill for 3 years, and my boyfriend finished (outside of me) without a condom very close my area. My period was starting to end when we had sex today and I took the first pill of a new pack this morning. Are there any chances of pregnancy? Thanks!
