Positive vibes please

Got a positive pregnancy test yesterday! Then today my husband got home and he wanted me to take another on , so I went ahead and peed on the stick and the test seemed slight lighter, the clear blue digitally says positive but I’m just worried .

I’ve had one chemical , one successful pregnancy with my daughter and now this one . I think me and my husband are just so worried from the chemical we had two years ago , we are just traumatized. We feel like we are holding our breath,.
