2 weeks ago I gave someone a blowjob and made him ejaculate with my hand. I saw precum before he came but am unsure if any got in my mouth. I then went him and showered. I don't remember if I drank anything or rinsed my mouth. I then sucked my dildo and briefly put the tip inside my vagina. I used it to touch myself and orgasm. What are my chances of getting pregnant from this? Could I have transferred sperm from my mouth? I've never had sex before and I am freaking out.
