Fear of miscarriage, help! 5 weeks 2 days pregnant

Okay so I’ve been trying to conceive for a little over 2 years . In that two years I never once got even the faintest of lines.

But 2 weeks ago only 1 week after ovulating I got a strong line , and now my test line is darker than my control Line.

That being said this is my first pregnancy, my biggest symptom right now is really sore boobs and insomnia/fatigue

Being that it’s my first pregnancy, I have a deep fear of misscarriage , I mean 2 years and nothing and now I’m pregnant , which I’m thankful. But how do I stop being scared

Ps. Watching YouTube videos on “early signs of miscarriages” BIG mistake

I think I’ll be truly gutted if anything were to happen
