HCG is barely rising/ Please advise

Lifeislovely • Mommy to one gorgeous boy and three angel babies. Getting ready to have my rainbow baby girl in February 2021.
Was bleeding lightly, but it seems to to have maybe stopped.  4 w2 days HCG  194. 5 weeks even it was 267.  Another test tomorrow at the lab.  No results until Monday because the office is closed.  I have fibroids that could be causing the bleeding, but with the HCG so low I'm afraid it could be 
eptopic.  If anyone has ANY experience with this (good or bad) please advise.  I've of course been crying, but I prefer to know what to expect.  I don't want to lose a tube if it can be avoided.
