So my last period was on 21+ and today i had sex with my boyfriend unprotected. We had sex for about 3 minutes and today is october 19. My boyfriend urinated since his last ejaculation and he didn't really reach his climax while he was inside me and i just blow jobbeb him for about 10 seconds then he came into my mouth. What are thechances of becoming pregnant? Yesterday I had severe cramps so could it be a sogn of ovulation or a sign that my period was coming? Thank you
