did your pregnancy go all the way after a vvfl ?

good morning I asked the question above because now that I'm ready to talk about my mc I noticed something very ! different with that baby vs the other two I have. when I tested with both my other kids the line popped up quick and strong which to me would mean a lot of hcg which is good,but when I tested with the baby I lost I notice all my test were vvfl which I'm lead to believe meant low hcg thus the mc so I'm wondering has this happened to anyone else and the opposite happened? fyi yes I tested around the same time with all my pregnancies so I kinda felt like something was off about the last one before it happened
