3 rounds of sex

So my boyfriend and I had sex 3 times the day after my pills for my last pack ended. My period just ended the day before and there was a mix up at the pharmacy, so I haven't gotten my new pack of pills yet. So I didn't get the first pill of my new pack and we had unprotected sex 3 times in a row. He didn't cum in me any of the times but I'm still worried. Do you guys think I'm ok? This all happened last night by the way. I was supposed to take the first pill of my new pack last night at 9:30, but I still don't have it. And we had the sex last night. My period ended Saturday. Should I be worried?
