A Week and A half Late for AF!

Ma
I have been expecting AF on March 1st, I'm still late. I'm not sure what's going on, i have pcos and my periods have been regular lately. 2 days before my period I went to the bathroom, wiped and had creamy milky discharge mucus. A week ago, I was experiencing, some cramping, sore itchy breasts, mood swings, cravings, got very tired the next day, and very irritable. This week, on Saturday I started cramping only on the left side, my lower back and belly and pelvic area. No bleeding still. Also, ive dropped 20lbs the week of my period, then after the week of my period i became nauseous all day, headaches, teeth sensitivty, and bloating.Took 2 blue dye tests and got BFP in the time frame. I took 2 pink dye tests and it was negative, then took a digital it said not pregnant. Should i wait and see? Or what should I do? I've been trying to have a baby for a year and a half now.
