Another chemical pregnancy or could be actually preggers?

Last month I had a chemical pregnancy on the Dec 26th as it shows on my calendar my bleeding lasted for 7 days and I had 0 hcg at my doctor appt on Dec 30th at the beginning of that pregnancy

I started out with hcg level 9 so here I am today my period is late two days today being the third I took a test and I’m getting a faint line on first response but negative on a cheapie both lines are pink but I would be 4 weeks 4 days if I were pregnant why would the line be faint could it be another chemical maybe this I took a FRER test on the 8th of this month and it was negative no faint and now I’m getting a faint 🤦🏾‍♀️ all of this is so stressful and confusing !
