Confused.. spotting at 4 weeks

Hi!

So CD 27 I got a very faint positive on frer and clearblue early. The next day (CD 28) I was spotting brown and light pink.. very light amounts but still noticeable.

Today is CD 30 and I did another test which is darker. I am still spotting brown and pink.

Has anyone had the same and what happened in the end? I had a molar pregnancy exactly a year ago and it started out with spotting😩 so I’m worried it’s that again.
