Early signs of pregnancy?

Positive Vibes

Hi all im 9DPO 5 Days until my predicted af arrival. Today i noticed consitant lower back dull pain and then it went around to my right side of lowerback/hip. I cant say i realy had this before its very much similar dull pain and tension you get in the lowerback right before you get your period. I have also felt a deep dull discomfort slight pain in my right side overy at 7 DPO. Could this mean somthing maybe related to possible early signs of pregnancy? Today also felt bloated and and discomfort as in heavy feel in my stomach and had a deep dull pain on my left side of my breast mostly on the nipple. Just curious if any of you experienced anything like this before a positive result? Thanks in advance x
