How accurate ?

Ky • Married to my best friend👩🏾❤️👨 Living in Europe Mommy to Marcel 🌈👶🏽

I know this sounds stupid but I picked this up at family dollar and I'm wondering how accurate it is... my period calendars have been super off and have given me two different days and I'm still waiting but so nervous to celebrate this bfp as we've been ttc for 7 months now. Just tell me is this real..should I test again in a couple days...should I tell my husband now or later
