Just found out im pregnant

Period is due in 3 days. I have some light red blood once when i wiped 3 days ago and had cramps like period so was sure my period was coming. But as i had no more bleeding i decided to test and got a very faint line. I am still crmaping. Its not severe but feels like period pains. I have a little girl and cant remember what it was like with her. I also had a chemical 2 months ago and so scared the same will happen again :-(
