Beta levels

Who had beta level at 12 and it went up in 48hrs last period was November 20 supposedly ovulated December 7. Bleeding only to wipe dark red nothing to put a pad on it’s only every other day. No cramping just extremely tired little dizzy spells. And bloating I had  constipation. but after the er visit I have been going. I’m new to this pregnancy thing and terms. Just want luck.
