Can you get pregnant before period?

What I mean by this, so me & Hubby had sex like a couple days before my period initially started. He came in me multiple times approaching my period date. I was 2 days late on my period. Then it started, but this period was completely odd. Day 3 I became light and stopped bleeding heavy then day four it came back. My period is usually 8 days long but it became 6 days. (No brown no blood). This period was a little different but it had some flow to it. It was just not the typical period I usually have. And the only thing I can think of is okay he came in me before hand I was 2 days late then it started. Could I possibly be pregnant???
