Should I worry?

A few days ago I got a faint positive on a pregnancy test, the past 4 days all positive and have been getting darker, 2 days ago I started spotting and then it turned heavy and clotting up until today and it’s barley there anymore.. what’s going on? And now it’s nothing on a pad? Just when I use the restroom.. and it’s turning pink and not spotting anymore.. I took a test today on a strip and I never got faints on one even when the past few days I got it on a frer and not on a strip the tests were darker even the day I was spotting it was a darker line. Now today I have a faint on a strip and it’s there and pink.
