too early to test ?

So my hubby and I have been TTC for 3 months now and this month I'm 3 days late and no signs of AF except upper back pain ( first time I get this pain ) And no other symptoms expect sleepy and a stuffy nose , tested 5 days early and got a negative on the digital test but I'm too nervous too test again :( ANY ADVICE ? Xx 😫💕
