Please help..bfp on clear and then this ....

Please help. I took a dollar store test 3-29 vvfl (first pic)

Then took a clear blue digital 3-29 bfp (second pic)

Now today 3-30 took a dollar store vvfl? Idk (third pic)

I had a misscarriage 6 months ago, am I just freaking my self out?

Also had light pink,to dark red with 1 very tiny size of a seed clot on 3-28 but all only when I wiped and very minimal light pink spotting on 3-29. No bleeding or anything today 3-30.

Should I be worried.

I'm just nervous because the dollar store test I took today (pic 3) in person is almost impossible to see the line....please give me some advise.
