Spotting?!

Heather
Okay ladies, I just got done with my period about a week ago. I am on the pill but I messed up and missed two days..I know, I'm sorry.. My SO and I had sex on both days that I missed my pills and he came inside me. Now I'm having little mild cramps and very light spotting. Not sure if I'm sporting because I didn't take my pill and my period is coming back, or what! Please, any help??
