Suggest Treatment For White Vaginal Discharge After Periods

Im 9 days late for my period and have been regular for the past 3 years, ive not been on the pill for a year and its the first time so late, i have nauseas mostly every evening and strong smells make it worse, more frequentlygoin to bathroom and mix of diarrhea and constiption, swollen boobs and last 2 days very bloated around stomach area. I did a test 4 days ago and came back with two lines but one every faded. My last period last end of march. I started to get tired and the rest of symptoms before my period should have come and now starting to get white discharge after a week of none of it. What could it be if the test was negative
