Confused?

So I am currently 3 days late for my period (which is always regular)and have been having lots of symptoms as far as sore breasts, tiredness, and nauseous feeling in the past week. My husband and I have been trying for about 2 months now and so far have not had any success... I have taken two test so far and both have shown negative? Am I jumping the gun to soon to test? Just not really sure what to think and need some guidance pleaseee
