(TMI) sore nipples

Let me start of by saying I'm hopping to be pregnant,Ok so my cycle is due in about five days, my breasts are slightly tender but noting painful when my cycle is near. Never have my nipples hurt, for the past toe days now when they are touched a slight painful tingle occurs! Not sure how to feel, don't want to take a hpt because I've been dissappointed the past few months with negative results  ?.....what to do?!
