Chances of Missed Miscarriage??

Lo

I've had 2 missed miscarriages prior to this pregnancy (at 9 weeks each time).

Just had a scan at 18+3 and all was fine. All bloodwork has come back normal as well.

So my questions is, what are the chances I'll have a missed miscarriage or something will go wrong without any symptoms? Terrified that I won't bring this baby home either 😭
