Question! My period was 5 days late. I tested with a FRRR and it was negative the day before period was due. I usually have no symptoms of AF even during it.

I started after being 5 days late.. but it's not heavy like it usually is..... I usually sorry, TMI bleed through a ultra tampon every 2 hours for at least the first day,, but I have barely been going through a light... I am so confused because my boobs hurt, I had really bad cramps yesterday(like I was hunched over crying), I have been very nauseated in the am...... any advice?
