Last Saturday, I was intimate with my date to my homecoming dance. We did not use protection, and he didn’t pull out. He asked if I was on the pill. I said yes. That was 9/29. The last time I took my pill was 9/25, as that was my last pill in my pack. It wasn’t my hormone, since it was the last pill. So the last time I took my hormone was 9/18. Is there a chance I could be pregnant? I’m just a little worried
