Pregnant?

I’m on the pill and my boyfriend and I did not have sex but he did rub up against me bare. I had light spotting and I was suppose to get my period today but I haven’t and sometimes I’m a day or two late. I’ve never have and it’s been 6 days since we did that. Is there any possibility that I am since or just freaking out for nothing? He didn’t have any semen on him at all when he did but I’m just freaking out.
