When should I take a pregnancy test?

Hi everyone. We are on month 5 of ttc. It is 36 days since my last period—-I typically have a long cycle. Roughly between 32-37 days. We really baby danced this month so I feel very hopefully. Typically when I am about to get my period, the week before my boobs are so sore. I am not experiencing any of that this month. I am to be getting my period tomorrow (according to the app). I do not have any symptoms of anything currently. When should I take my first pregnancy test?
