I’m scared

So my periods are ALWAYS on time. This month, I got all the normal period symptoms and everything and got my Period right on time but for the past 4 days my period has been very on and off. One minute, a bunch of blood comes out then stops and this happens all throughout the day. The color of the blood is just how it always looks (not pink or brown like how in plantation bleeding looks like) but I’m just scared bc me and my boyfriend have been having the pull out method (I’m not on BC) and nothing has happened before accept this mouth my period is being weird. Another thing I should add - I have been very stressed out and kind of depressed lately so maybe that has something to do with it?? I don’t know..
