10 weeks and 1st appt tomorrow!

Okay ladies I need y'all right now..:

So I'm about 10weeks (or so) and my first doctors appt is tomorrow. I'm super stressed because I just want to know that everything is fine and my little nugget is healthy. But, I can't help but to worry about all these terrible things... can anyone tell me what an ectopic pregnancy is? Or the symptoms associated with it? I haven't had any bleeding or anything weird. And no morning sickness.. just really tired all the time. If something was wrong at this point, I'd know right?

Thanks y'all 😊
