Positive blood test

Hey mamas I hope I’m not jumping the gun by joining glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> so soon I barely just got my positive today at 8dpo 6 days till period and still wanna make sure I’m not getting a false positive. But my question is can I get a positive blood test at 8dpo?? I went in to get one as soon as I found out and wanna know if my results will be accurate. Picture of test (jus cuz I’m still in shock)
