Chances?

Dont judge I just want an opinion before i panic a little bit. I am on birth control. I was on my off week and didn't have a period really. I spotted for like a day that was it. I started the active pills again and forgot to take it for 3 days and on the middle day I had unprotected sex. A week later I spotted for 3 days than had unprotected sex again(same guy I'm not a whore I promise). Anyways what do you think my chances of being pregnant are? edit: Well it's my off week of my bc should have period but my last one was late so im not sure. I wiped and there was blood a few days ago but then nothing after that.
