Could I be pregnant?

My period is in 9 days. But I had unprotected sex the 25th then the 27th and then the 1st. I didn’t think about it and then took plan B the 5th. The 25th and 5th are many days apart from each other. Then on the 5th I also got the shot. I haven’t had any spotting but basically I waited a whole week before I took the plan B.
