Pregnancy scare help!!!

I’ve never had sex with complete penetration, but my boyfriend’s penis has rubbed around my vagina and he’s fingered me after he came. This happened for the first time Thursday, I spotted on Friday, and missed when I should have started my period yesterday. We didn’t realize there was a chance you could still get pregnant from that.

We’re going to Planned Parenthood tomorrow to just hear some advice/facts from them.

Should I take Plan-B in the morning?
