Im feeling a little different :/

Tylah • 25 years old.. 1st baby born 3/12/15 😘😘
Okay so im 3 days late . And i have been having lower backaches , alot of white discharge ( no odor , no itching ) sore nipples and very dark aereoles .. Im just feeling different but i dont wanna jump the gun But i never had any of these symptoms before except the sore nipples . I also didnt get any implantation bleeding which isnt always common . I believe its too early to test ima give it about a week or so .. Does anyone else feel this way ? Please help !!!
