plan b.

So my BF and I had sex last night. He started cumming inside of me and then was like "I came inside of you" and then I was like okay... well he freaked out on me and told me to take a plan B. Luckily I keep one just in case so I took it. Now I'm nauseas which I read was a common side affect but now I'm spotting. Is this normal? What are the serious side affects of plan b. This is the first time I've ever taken one.
