Bleeding positive test.

Hi All

Wonder if anyone can help, put it in points to make it easier to read

Blush pink/ brown spotting 4 days bfp

Then two days heavy bleeding

1 day light

Then just a bit last few days

Then took a pregnancy test to to 100% check and it came back positive.

I did a second one to make sure. Should I be worried about bleeding?

Should be able 4 weeks pregnant.

Thanks
