What is the chances of getting pregnant on my fertile day, no penetration, no ejaculation but just having genital contact and his penis touch only a few times near my vagina with little of pre-cum? I know this a low chance but how many percentage will this lead to pregnancy. I'm really worry and paranoid. My period is due 5/5/2011 but my period never comes right on time and I see brownish, red like discharge before period. I been tired a lot lately but that doesn't really help. I don't think I have any other symptom of early pregnancy other then being tired and only having brownish and red discharge. I also took a early pregnancy test at 5/3/2011 and it comes out negative. I am planning to take it again next week. For now, should I be worry? I can't afford to have children.
