I dont know what to do

Me and my boyfriend did stuff and at one point his dick was touching my vagina. He did not cum but theres a chance that he precummed, is it possible to get pregnant from this? I was supposedly ovulating that week according to the glow app. The glow app predicted that i would get my period yesterday so I am one day late. I know its too soon to tell but Im really hoping this isn’t pregnancy and maybe stress related because I’ve never missed a period in my life.
