Low Hcg? I think I'm losing my rainbow

Ho
On Monday I had betas done at 14dpo.  They came back at 30 hcg, 12.8 progesterone.  My OB started me on vaginal progesterone supplements tonight (16DPO) just in case.  Went in for a second beta draw this afternoon and I just have a terrible feeling it's not going to have doubled.  I can't be losing my second pregnancy too.  I'm going to need to be committed to a psychiatric hospital.  Does anyone have any encouraging stories about low Hcg levels in the beginning?
