I am terrified of all the things that can go wrong

Hello all… this is the first time I’ve been pregnant and I’m just worried about all the things that can go wrong. I didn’t think I’d be like this, but I guess I am lol. But I’m just worried about the cramping and what if it’s an ectopic pregnancy or a blighted ovum. My love for knowledge and learning has, in a way, cursed me. I won’t go in for my first appointment until 8 weeks (July 7th). Nothing has been wrong aside from the occasional light cramping, but should it still be happening into the 5th week? Idk what to expect and I worry for absolutely no reason 🤣 I’ve been known to over think. I want to believe that everything will be fine, but of course my brain likes to remind me of all the things that could go wrong. Any advice would be lovely!!
