4 days late and BFN, so frustrated

Hubby and I started TTC this month. I'm 4 days late but have been getting negative test results. I have no period symptoms qhat so ever. My period is 99% spot on with the app. Not sure what to think...

When I was 21 I had an abortion, I'm 31 now. Before anyone judges, I did what was right for me. The guy was a random hook up, had also gotten his ex gf pregnant at the time and I was not about to go through or put a child through all of that.

However... at that time. I got what I thought was my period the first month after many negative tests and a few days late, missed period the 2nd month only to go and find out I was 9 weeks pregnant so I had negative tests for about 7 weeks and then finally a positive and found out I was further along then I thought.

I'm hoping this is not a repeat of that time because that's a stressful wait for me when we are TTC. But idk what else to think. 😞
