Okay ladies. I need opinions. I had sex with my bf 3 times between yesterday & today without condom or birth control... (Irresponsible, I know.) He did pull out. Ruby says my fertile window ended 6 days ago. Should I go get plan B right away? Should I be worried? I got pregnant last year & miscarried at 3 months so I don't really want to ruin any future chances of getting pregnant but now is not the time..
