Advice please :( !!

Karla
I'm a week late and I've done two tests and both negative! I'm in my 20s and me and my partner have been trying for a baby.
My boobs don't hurt though, sorry if it's TMI but I don't feel any different ... Does anyone have any advice? Am I doing tests too early? Could it take longer to show?
I'm never ever late so it's super strange!
Please help :(
