Could I be pregnant?? Please help

So to cut this short, I’ve been seeing this boy for a couple of months. I don’t wanna go on the pill due to having bad experiences with it in the past - weight gain, headaches and depressive episodes which I never had before. So about 3 weeks ago we had unprotected sex and I took the morning after pill so that’s all good. However, the week after we had unprotected sex again (I told him to use a condom and he didn’t listen) and when I went to get the morning after pill the clinic was closed. He came inside me about 3 times so this is very risky. But my period was due in about 5 days at that point so I’m no ovulating. There is no sign of my period it is currently about 2 days late. The boy is panicking as he thinks I’m pregnant - I have reassured him that the risk is VERY low due to the point I’m at in my cycle. However I’ve heard that the morning after pill can mess with your cycle. So am I pregnant or is my period late because I took the morning after pill a few weeks ago??
