how do you get happy after having a missed miscarriage at 12 weeks??? I'm excited but afraid......I'm really need mental support until hitting at least 13 weeks

I think I started testing as early as 5dpo not getting a faint positive til 3 days later on three different tests. So according to everything I'm only like three weeks............... I keep testing just to make sure I don't want to get happy nervous something may happen. I'm not even in a rush to go to ob it's like I just want to be on auto pilot until 12 weeks. I know there's a good possibility everything will be fine but I don't know how to feel. Low-key excited this a my second chance.......
