TTC after miscarriage. When to test ?

So, I had a miscarriage on 1/4 and have been off birth control ever since just to let my body go back to as natural as it can. Periods became normal and regular in April and me and my SO have been TTC every month since. This month I was supposed to start my period 7/29 according to eve* but I usually start a few days before but I’m LATE for the first time since last November when I got pregnant. I have been having hot flashes and really bad heartburn the past 4 days as well as clear/white discharge. I’m just wondering when I should take a test. My heart is scared but also hopeful. Part of me wants to get a test after work and find out but I don’t know if I can handle the disappointment. Either way, do you think it’s too early to test? Should I wait? Or go grab a test RIGHT NOW. Please send baby dust. ❤️😭
