I’m brand new to being pregnant, ever, at 31 yrs old with no miscarriages in the past. I’m 4w6d with my HCG blood test revealing that I was at 650, 3 days ago. I’m just curious if there are early warning signs that one would be miscarrying, I fear that everyday, as I’m sure we all do. If I had strong positives since I found out 3w5d would that be a hopeful sign? I don’t have any bleeding just mild cramping on n off. These normal signs?
