First time taking Plan B!

Cassandra
Hiiii! So I had sex this past Monday and the condom broke and we don't know when. He didn't finish inside me but there's always the precum. He did end up finishing but he pulled out and we were safe there. We had sex the last day of my period too. We got glad Plan B right away and I'm having not the best side effects. I'm cramping, spotting and I'm emotional. Is this normal? Someone please help my anxiety.. :(
