What Are The Chances Of Getting Pregnant After Non-penetrative Sex?

Hello doctor, i m a 22 year old woman. I am very much tensed for last few days. Please help me. I m willing to know about the chances of getting pregnant without having sexual intercourse. I had some wonderful time with my boyfriend. We both touch each others genitals. He inserted his fingure inside me. During the whole session he did'nt ejaculate and only had little precum. And now i miss my period by 11days and also experiencing soreness in nipples. Please do reply. I remain grateful to you forever. Thank you for your time.
