My last period started on the 19th Jan. On the 26th Jan, me & my boyfriend were making out & we rubbed our gentiles against each other, no penetration at all. But when he was about to cum I got off of him. He ejaculated but away from me. I'm worried about pre-ejaculation & if he had touched his semen and touched me afterwards, he didn't insert his fingers tho, only rouched the outside of my vagina. I took an Emergency contraseptive pill 4 hrs later, another one 2 days ltr. Chances of pregnancy?
