So I haven't exactly missed my period. I started on Sunday of this week (August 28) I was spotting and it stopped later that night. I had taken 2 pregnancy tests throughout the 4 days after it stopped; they were both negative but I also think that I took them at the wrong time but I'm not sure. I've been having mood swings since 3 days before my period but that could've been PMS; nausea and fatigue around the same time; abdominal and back pain for the last 2 days and white discharge since yesterday. I don't know what's going on and I need answers.
