My girlfriend and I had sex a few days before ovulation and condom broke but pulled out right away and wasn't even close to cumming. Maybe a tiny tiny bit of pre cum. So we took plan b about 24 hours after and now 6-7 days after taking plan b I have spotting. And it's 5-6 days after I should have ovulated :( could this be implantation spotting or from plan b? Thanks I'm really scared.
