Im confused!?

Okay ladies so I have like 4 period trackers and 3 of the 4 told me I was suppose to start 4 days ago. This glow app told me I was supposed to start yesterday. I havnt had any sign of my period other than being bloated. Every morning for the last 3 days when I wake up and go to the bathroom I have like a pinkish tint when I wipe except this morning. There was nothing. So I took a pregnancy test and got a negative.. im suppose to go see my Dr today so I'm gonna be talking to him. My boyfriend thinks it might be to early to test but idk. My period has never been this late... am I over reacting or what
