Is this a good sign

C

I had a miscarriage at 11 weeks in June 2020 and a chemical in October 2020. I haven’t even missed my period yet snd got theirs line progression from 10 dpo. Is this a good sign that it’s a strong pregnancy or am I just grasping at straws here? My chemical was definitely not this strong so early, I didn’t even test positive until I had missed my period, so this is feeling a lot more solid but I also heard that line progression is BS. What do you all think??
