Am 26 Yrs Old Female. I Want To Know If

Am 26 yrs old female. I want to know if am pregnant. My period is due this week. I have headache, mood swings, lower abdominal cramps, white milky discharge, thigh ankle pain, food cravings, gas problem, increased saliva secretion, nausea after having food, sweaty feet n palm. Not sure of my ovulation date but could be 10-14 dpo. Felt dizzy only for a day. Feeling tired and sleepy all day for no reason.
