Am I pregnant

Desarae
My boy friend and i havent had sex for like a month or more we just have oral. When we do oral he always ejaculates on my body (like my stomach or breasts) and we always clean it up right after hes done. I do rub his penis against my clit while giving oral but he doesnt go in me or ejaculae around there. I missed my period by one week now, could i be pregnant?
