Hcg 12 dpo

Hi ladies, I have a shorter cycle, usually around 26 days. I'm pretty sure I ovulated on Sat 11/7 or Sun 11/8. Took a FRER on Wed, 11/18 and got a very faint barely there positive. Had a beta hcg drawn yesterday, Thurs 11/19 and it came back 19. My midwife wants to recheck it tomorrow and check progesterone. I found a chart that says 17-200 at 14 dpo is normal. Any ladies out there have low starting hcg and went on to carry full term, healthy babies?
