Miscarriage

Ok I had a miscarriage back in April does a miscarriage change your body that much? I ask because before I miscarried I had implantation bleeding two days before my missed period then on the day it was due bfp. Now this time around first I have never spotted while ovulating and I did on last cycle this period I got was about two days late according to my glow app but can’t even call it a period all I have been doing is spotting pink brown no bright red I’ve taken test they have all come up negative so I’m going to do a blood test tomorrow just wondering if anyone on here has experienced the same thing of close to it?
