Not sure what to think

So I stopped the pill about almost two months ago. I had my period 6 weeks ago, nothing since. For the last three days I’ve noticed left side pain (like mild cramps) nausea and loss of appetite. Me and the hubby are not trying and have been using the pull out system. I took a test almost two weeks ago to make sure and it was negative which if I was pregnant only about two weeks... could I be?
