pregnant possibilities

Taka
So.. my bf and I are messing aroud and rubbing each other.. 2 days after my period. I'm not sure if he pre-cummed while rubbing, and according to glow I have 3% risk that night, is there any possibilities that I could be preagnant? 
And I still have 7 days before AF but I'm having cramps. I ovulate 7 days ago
