My gf and I have sex yesterday and I was worried if she is gonna be pregnant. She did blowjob me first and I cummed. Later, she wants my penis into her vagina, and I did. Im now worried, what if that residue of the semen in my penis can make my gf pregnant. 

 

I inserted my penis 30 mins after I cummed. I washed up my penis, and screwed her. While Im f*****g her, I can feel I was about to cum again so I pulled it up.

 

Is there any chance of getting her pregnant? TY

 

PS: She is on her 2nd day of period when we did it.
