Getting nervous. 1st pregnancy

I don’t know if it’s just me but today I’m 4 weeks and I see all these posts about chemical pregnancies and it scares me. This is my first pregnancy so the worry that I could possibly lose this little love is so real. My lines have been fairly faint but they’re for sure there. I want them to get darker so badly so I can feel a little better. Maybe my emotions are high because of hormones? Or maybe I’m just worried for no reason? I guess I just want to know I’m not alone in feeling like this.

Anyone else start feeling that way during their first after seeing all this talk about chemical pregnancies?
