Hello I am 20 yrs years old Andi usually have my period between the 25th and first I even have a calender on my phone that I keep track of my period. I was supposed to have it the 28th thru the first and I've missed my whole period. I took a pregnancy test and came out negative. So i'm wondering if maybe I should contact planned parenthood or just go to a doctor. I'm gonna wait til i'm seven days missed if it doesn't start by then i'm probably going to take another test but I have huge breast soreness and discharge everytime I think i'm starting I go to the bathroom and check but its only discharge.. please help
