tww is driving me insane!

ugh this wait is intense! i am 6 dpo. 8 days till AF is due. my boobs have noticeable veins on them and are so sore the nipples especially. my nipple are more erect and bigger looking. oh the actual nipple part has tiny white dots on them. ive never noticed that before. i have slight cramps. my cervix has kinda been all over the place so not really sure what to make of that. the mucus has been a mix of water, creamy, and sticky. is 6 dpo to soon for symptoms? when should i test?
