8dpo?

So I'm assuming I'm 8dpo. I seen ewcm the day before glow said I ovulated. Anyway, since the glow ovulation prediction, I've had faint cramping all around my uterus, it changes places every time, the cramping is off and on. Today at 8dpo I've felt a tingling feeling in my uterus it only lasted about a minute or 2. I've had mild lower back pain that only started today. At 6dpo I had a metallic taste in my mouth. It only lasted the day. My boobs feel sore while wearing a bra, when i try to feel them without the bra i cant pin point where the pain is. When wearing a bra it's on the lower side of my boob. The top of my thighs feel sore, but then I've also been on my feet constantly for the past week. I've noticed that I'm weeing a lot more. I know I should wait until af is due, however what are the chances of me getting a positive tomorrow (9dpo)?
