Hello!

My HCG levels were 13 yesterday and I am about 4 weeks pregnant. We say about because I has my son 3 months ago so there is a chance my dating is off since my period and ovulation can still be off track from having my son. The dr said she is concerned but has seen levels like this in the early stage and to hope and pray my levels go up they way they should. But I'm very concerned as I had 2 miscarriages before my son. Has anyone had low levels before and what was the result? I just need to either set my mind at ease or start preparing myself.
