HCG levels....help!?

Caitlyn • Married 💍 Mommy of 4 year old boy and 6 month old baby boy💙💙 fur baby yellow male lab 🐶 love all my Berry boys!
Hey ladies! So yesterday I got my blood drawn to check my hcg levels and they came back at 189 and as of yesterday I was 4weeks and 4-5days pregnant. They called me this morning and said that my levels were normal and right on track but 189 just seems low to me for almost 5 weeks pregnant? I'll be 5 weeks tomorrow. Anybody have any hindsight on hcg levels or similar experience and had healthy pregnancies? I'm only concerned bc I had a MMC last February 😞 so just want everything to be happy and normal! The only symptoms I really have right now is one tender breast and the other only is tender to the touch? Thank you!!
