Help please!! TMI no pictures

Has any one had bleeding at 4weeks it wasn’t extremely heavy but it’s wasn’t very light it was dark red now it’s only when I wipe some brown now no cramping really i go in tomorrow for my second HCG levels but I’m afraid I’m miscarrying again the pregnancy tests are getting darker but they did that last time to. Last time I had a lot of blood with lots of little blood clots bad cramping in back this time I maybe had one small blood clot and little to no cramping at all and it’s almost all done now.
