Symptoms

okay so lately my nipples have been so sore and getting worst little by little, my mouth has seemed to be sorta dry making me more thirsty than usual so im constantly peeing.. not sure if thats a symptom or if the frequency is because im drinking alot of water. and also ive had lower back aches idk if i should take these as pregnancy symptoms cus its been going on for days except the back aches. they just started yesterday and my AF is due 1/28
