PTSD after two miscarriages

Don’t want to sound dramatic but I’m currently 5 weeks pregnant after two miscarriages and I feel overwhelmed and sad.. I wanted to be pregnant more than anything in the world but now I’m just waiting for my baby to die, waiting for the blood, or worse thinking everything is okay going for a scan and hearing “no heartbeat” again, I just don’t know how I’m going to cope with all this, have I made a big mistake putting myself and my mental health through all this so soon after two miscarriages 😩😩😩
