4 Days late🚨

Hi! I’m now 4 days late for my period. I took a test three days before my expected start date and then one on the day I was supposed to start. Both were negative. I do know that maybe I ovulated later than expected but I’ve NEVER had irregular cycles. I’m terrified of seeing another negative test. We have been trying for 6 months. Should I wait until at least one week (3 more days) to test again? Has anyone else had this happen before? Were you pregnant or no? I need opinions or really just some advice or kind words.
