Am i pregnant and have a urinary tract infection?

i have been getting light cramps, my period should be here the 6th so cramps are early and hip pain. i have been very moody and have had heartburn which is accompanied with an upset stomach and nausea. i have been more tired and hungry lately and i have been peeing more often but not much pee is coming out . my viginal discharge has been thin and milky with a light weird smell, not a fishy smell. at night i cant sleep and only sleep 4 to 6 hours. i normally sleep 8 to 10 hours. when i get up from laying down i get dizzy and i have had bad gas. my breast are lightly sore which is much less then what is normal after ovulation. the smell of fried food and new products made with plastic make me nausea. and i have had light back pain. am i pregnant and have a urinary tract infection?
