Mom's help me I'm so depressed

hello everyone long sad story short is I have had 2 miscarriages in the past year. Well just last week we found out at home through pregnancy test that we where pregnant again according to my last period I am 5 weeks and 6 days pregnant today. My doctor got me in quickly because I was in the e.r for sharp pain in the womb area the other night, well at the e.r they tested my hgc and it was only 50 2 days later I saw my doctor and my hcg only went to 75 I know this is bad and extremely low is this another miscarriage:(
