Which brand pink dye ?

Which brand do you recommend the most ? I am now 3 days late , never had pms in my life Other than cramp the day my period starts. Past week I’ve had sore and puffy breasts , light nausea like if I’m car sick , been tired and had wired cramping . Not painful , like a dull twinge or stretch , basically not like when my period starts. I took one clear blue digital and it was BFN 4 days ago . Took their non digital version and was left with an indent line 3 days ago. 2 days ago took another and the bottom of the pregnant line started at the bottom and then just stopped before the middle . I have one digital of theirs left and don’t feel like I trust it lol my doctor wants to wait till Monday to schedule a blood test

Backstory:

10 years ago I did IUI, got pregnant with twins . No urine tests would come up positive. It was before my period was due . When to do some blood work for my fertility doctor and they checked HCG even though he didn’t ask for it and that’s what I got the call I was pregnant. (My boobs felt the same bow as they did then) sadly I miscarried shortly after
