Am I pregnant ?

Bottom was from yesterday (which I know is “not accurate” but it did change in color. Started as a shadow and grew into a light pink) the top was this morning. I’m due for my cycle on Sunday so I’m just curious. I’ve had a ton of lower back pain, and some heavy nausea on/off, I definitely have food aversions/smell, some normal cramping and around my belly button. This would be my third pregnancy, so I’m pretty sure I am pregnant…. But want other opinions before I surprise my hubby !
