Pregnant while hcg is present

Markeisha

I think I miscarried on January 16th I started bleeding Jan 11 through Jan 22 I BD almost everyday after and I heard that you ovulate two weeks after miscarrying but I’m not sure if I did because there is still hcg in my body so every time I take an opk test it shows positive same with a pregnancy test it’s faint, and I’m spotting sometimes brown sometimes pinkish red, how will I know if I’m pregnant do you think I could be pregnant ?
