I’m so nervous🥺

I’ve only known 4days& I’ve taken about 20 test,, 🥺but I just can’t stop worrying, I’m 25 me and partner weren’t trying per say but we weren’t preventing anything.. I just have the worse feeling because when I was 17 I had an abortion and I really keep thinking what if something goes wrong because of what I did when I was 17😞.. i’m so emotional I can’t stop crying every-time I think about my baby I can’t stop being scared that I might loose him/her I’m trying to stay so positive but I can’t help but feel like something might go wrong💔 I just wanna be happy I’m pregnant but I’ve so scared.
