confused

I got the paragard in July and was on the depo shot for over a year. My cycles have been irregular but I always have a period starting the 4th of every month. I am due today but idk if I am showing signs of my period coming or not. My boyfriend and I do not use protection. I have very sore breast to where it hurts to wear a bra and have a cream discharge (no odor) and some sharp pains, I would not describe them as cramps. I suffer from pmdd and endometriosis. I don't know what to expect. Am I going to start my period soon? I'm not use to getting a period. I have always been in the shot or the nexplanon. Never got a real period til now.
