Chemical pregnancy

Alicia • Got married Nov. 8th, found out I was pregnant 12/9... It`s been a crazy and awesome month
Does anyone know at what week you can feel safe you won't have a chemical pregnancy. I was suppose to start my period yesterday and still today nothing, but I'm just worried. I'm gonna call my dr. Today to try and set up an appointment. But I feel like I should take a test every day just to ease my mind lol ( I'm sure that sounds crazy)
