First month off pill, 8 days late but negative result

My husband and I started trying last month, I took my last pill on New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, had my period 6-11th Jan as normal but nothing since, took a test last week and and a digital yesterday but both negative.
I know it takes a while for your body to get back to normal after coming off the pill (I was regular before starting the pill) but is it normal to completely miss a period or could I still be pregnant?
