So scared help

So am 4w5d and yesterday at work I notice I was spotting so I put some paper since I had nothing there for the time being when I went home and use the restroom there was much more dark bright red blood so scared the bleeding still going and now am passing small clots does this mean a miscarriage?? I called my doctor but told me to just wait it out and see she’s sending me to check my levels later on today sooo is this it again I’ve failed I was so excited and happy we had stop trying for a while and finally had got our BFF!
