Am I miscarrying?

Today I went for a blood test confirmation and am waiting for the results.. Couple hours later as I'm waiting for the call I noticed a little pink on the toilet when I wiped.. About an hour or so later it was brown and still only spotting. Now it's more reddish brown and is more like a light period I guess.. Still not as much as my period normally is but heavier than just spotting. I'm not really cramping. Does this mean it's over? I've heard of women having periods while pregnant.. But I really think it's over for me. I was 4 weeks 2 days today. Guess it didn't work out for us to get our rainbow baby just yet. Idk what I'm doing wrong😭
