Pregnant or Not?

I haven't felt any different it seems and I'm on the the pill for 2 1/2 years now but this month I missed two days in a row, but took them immediately after I noticed. My fiance and I have daily sex but I haven't noticed any cramps or anything. my period was suppose to happen Monday, is it possible to be pregnant? My fiance dosent really care that much if we do end up having a baby but I'm not ready yet. I'm shaking so bad.
