My bf and I were making out and then it's gotten pretty serious. I noticed how his penis have this fluid and I tried to wipe it off with my mouth with a bl****b and then it was dry and then he rubbed his penis on my naked vagina but he wiped it off first with his hand. Then he told me to get off cause he feels like he's going to come so I did. I was worried sick when I googled it and found out that I could get pregnant from that. It's been a day since we've done this and we only did it once. I'm so worried, because I'm about to have my period in a couple of days. PLEASE HELP. What are the chances of me being pregnant from this situation and what could I do to prevent getting pregnant? THANKS!
