Help?

Hi everyone I’m extremely new to this I’ve only been trying to conceive since July this will be our first child. Usually my period comes on the 16th of each month so far after coming off birth control but this month it hasn’t? I’ve not really had cramps and my boobs are sore I’ve also got a sore back but that’s pretty common for me I took a pregnancy test 19th and it says not pregnant (clear blue digital) any advise on what to do?

I’ve booked in for an app with my doc on Friday just incase my period hasn’t came. I have another clear blue digital test in my drawer should I leave it till Tuesday or Wednesday the longer I hold off the more accurate the result will be?
