1 day late

AF was due 5/27 according to glow and I am always 2-3 days early never late. I have not been really stressed out at all. I had cramping only once a few days ago. Otherwise I just get this weird pinching on my right side. It lasted 20 minutes straight last week and I feel a sort of stretching feeling on my lower abdomen. I took an equate test and the lines did not come out just ink on each side. I woke up with a headache and I have had sore breasts for at least a week and also gained a few pounds fairly quickly. I also usually breakout when af is due and haven't yet. What do you ladies think?
