Pregnancy and discharge

Has anyone been pregnant but haven't had any discharge, not sure if I am pregnant and planning on doing a test at the weekend,my last period was on the 8/7/16, I've been threw the whole month with the normal discharge you get when going threw a cycle, my boobs have been hurting for about 2 weeks now, at first it was just my nipples, that's has gone now it just my boobs that hurt, been feeling very warm lately and very tired as well, I got cramps about 2 weeks ago as well, I've been tracking cm and cervix, high soft and closed but there is very little to no discharge can anyone give me a little insight to their experiences please many thanks 😊
