Hi, my boyfriend and I were being intimate, and we had genital contact, so our body fluids were in contact with each other. There was no penetration or ejaculation, however there might be some precum, or some extra cum that came out after the previous ejaculation. However, after a while, he inserted his finger into my vagina, and im afraid that some of his cum/precum might have been transported into the uterus. This happened about 5 days before my period was due and now I am a couple of days late. what are my chances of pregnancy?
