BLEEDING PROBLEMS, PLEASE HELP!!!! 😑😞😰

Has anyone ever had subcorionic bleeding before even testing positive on home pregnancy test? I ttc #4 and I've had one with every pregnancy but not until about 4-5 weeks and I had already tested positive on a home hcg test. But Iam bleeding and it's not my period no clots and it's doesn't sound like ovulation or implantation (but I did 3 days ago experience what I suspect to b implantation)or anything light pick to red if Iam avtive but if I just sit around I have no bleeding to very little light pink. Same symptoms of my others. Any ideas?
