pregnancy symptoms ?!?!

❤️Kim
6dpo and my breasts today have been so so sore , it's almost making me sick ! I have also had some creamy milky discharge (sorry if TMI) and I just now have felt the crazy erge to pee . Feels almost like a UTI coming on but no burning . I have not had a UTI in about a year . Ugh all these symptoms ! I did take a pregnancy test from the dollar store and it came back PFN, I know it's really too early for a test but wanted to anyways . I have some cramping , what would this be ?
