Bleeding at 4 weeks

So yesterday I noticed a a brown discharge in my knickers when I wiped later on it had pink on the tissue. Then this morning when I wiped there was fresh blood and a few clots.

I went down to the hospital and they did a test to confirm pregnancy etc and booked me a scan for Monday. They said they can’t do anything at this stage and have to wait it out but they think it’s probably normal. i have no pain at all

The bleeding isn’t heavy or thick and almost just like a brown tinge again now when I wipe.

Has anyone had anything like this and gone o. To have a normal pregnancy??
