Curious

So I’m just kind of confused and have no one else to talk about this to personally. Hopefully you ladies can help.

Me and my bf have unprotected sx. I had ended my period on the 27th of may First time he didn’t pull out was on the 27th as well. So I was nervous and went ahead and took a plan b on the 28th without even talking to my bf I just assumed that’s what I should do. I bled on June 4th on and off till the 7th. Since then he’s done it on the 8th, 10th, and 21st, of this month. Is there a chance I’m pregnant. I’m going crazy. Was my body resetting and bleeding those

Couple days as my period of June as well? I’m just very confused.
