Equate 5 days sooner faint line or false positive?

Me and hubby are ttc baby # 2 💓 this is currently cycle # 3 for us. It took a year and a half with our 1st.

This cycle I tested at 7dpo on a equate 5 days sooner and it was FAINT positive the next day 2 digitalis after that said no. I took 3 .99 cent red dye ones all negative. Ive been crampy and grumpy all week. I'm 5 days from A missed period. I've heard lots of negative stuff about equate tests (blue dye)... Has anyone got a positive on the equate sooner test and still was pregnant? I'm now 9dpo. But I dont understand why the other test are saying negative! Should I wait or test again??
