11 DPO AF 12/4...HPT???

Jackie
I am 11 dpo and my AF isnt set to come until 12/4. I had severe left sided ovulation pain for the first time accompanied by a small amount of dark brown discharge starting last Tuesday. This week I have been experiencing light cramping in lower pelvic, also feeling flutters in abdomin with heartburn. Me and hubby are so confused. Should I take hpt or wait.
