period spotting? implantation bleeding?

Anonymous

CD 33, around 13-14 DPO? cervix is open (not sure if its soft/hard, but i do know that this can vary) and im pretty sure open cervix means period is coming instead of pregnancy but i just wanna make sure whether its possible for this to be a pregnancy spotting. the only sexual activity i did was dry humping as well as giving my bf oral sex where he ejaculated in my mouth and i accidentally spilled a tiny bit of the semen onto my jeans (though i wiped it immediately and sprayed it with alcohol). what do u think?
