Scared and confused

So i got 4 positives 2 days ago. I retested tonight around 4pm-7pm, and the line was lighter. Could it be because its not fmu? Or am i in danger of a chemical? :/

Heres the first 4.

And here is just now

The picture doesnt do it justice, i can see the faint line in person.

Am i just tripping and everything could be fine? I bled a little bit (basically just spotting, i only saw it when i wiped) for about a week and when it stopped i got the 4 positives the same day. Im calling my doctor tomorrow but getting the fainter test is scaring me so bad i dont want to wait :/ this wasn’t a planned pregnancy but i dont want to lose it...
