Faint Lines??

I’ve never received a false positive, or an “unknown” result. My sister just took a test, and hers was CLEARLY negative. I see EXTREMELY faint lines...will test again in a few days, but just looking for second opinions....I lost my first born @ 34 weeks, and have been TTC for nearly a year...so I want to feel excited about this, but not have false hope either...thanks ladies 💕
