@Susan I’m 5 weeks already do you know if hcg can remain at same level in pregnancy ?
I’d say it’s left over from your previous mmc. 9.5 is very low and I don’t think it would indicate new pregnancy.
I'd test again every 2 days. That is the only way you'll know for sure. If the line gets darker, then you'll know it's a new pregnancy.
It takes around 5 weeks for hcg to fully leave your body.
