Miscarrying

I do not mean to offend anyone by this but it is my first time conceiving and while I am so happy I've never been so terrified I feel like every single post I read on here someone has miscarried once if not more! When I read statistics online it doesn't seem as common but on here it's all the time..just scaring me 😩also all the common pregnancy symptoms such as light spotting and cramping also contradicts by saying that is also signs of miscarriage! I need some reassurance here has any one had a successful first pregnancy?!?!
