LOW HCG LEVEL

Hi everyone! Is there someone here that has the same issue as mine. I am already 8 weeks 2 days pregnant ( per LMP). Last week i started to spot pink until yesterday it started to get red. It happens when i go no.2 or if i wipe. My hcg level last Friday is 47 then they repeated last Tuesday and its 79. The nurse said i need to repeat my hcg level today to see it trending down and she thinks I miscarriage. ☹️. She will ask my OB if i needed to get an ultrasound. She thought that i might have ectopic pregnancy. I have cramps and i work yesterday for 13 hours since the didn’t ask me to get some bedrest. I don’t know if my numbers are low since my period is irregular. I am so heartbroken. It’s our baby #2. Baby #1 is already 17 months old and i had this issue with him before when I’m 8 weeks pregnant. I don’t know if i will still hope that baby is okay or i will just think the worst. Sorry for the long post.☹️
