Hello, so I had sex 8 days ago. I used protection but I think the condom slipped. I took plan b 18 hours later and I started bleeding yesturday morning. It's heavy bleeding and it's something like my normal period. Can this bleeding mean pregnancy spotting or plan b bleeding that is suppose to be normal in women? My period is suppose to come in 2 weeks. Please help and share your thoughts.. Could this be a miscarriage?
