Ugh help

Blanca • Momma of 2👧🏼🧒🏼 pregnant with baby #3 🤰🏻

So I took a test with first response 3 days ago and I got a faint positive (top pictures

) and I took this one now and it’s negative it’s a different brand. I’m supposed to get my period in 5 days I think and I used a pregnancy test calculator and it says to test on the 17th but I couldn’t wait
