HCG raising after suspected miscarriage

Had my bloods drawn a week ago at 16 HCG (4 weeks pregnant)

Began bleeding as a normal period, cramps and clotting. Was ruled as a chemical pregnancy.

Had bloods drawn 6 days later (still bleeding) and HCG was 25 (5 weeks “pregnant”).

Has this happened to anyone? I really need some advice to ease my mind until my next blood test. Its been so emotionally draining. I’m over this whole process I just want to move on 😔
