I am 20 years old. I have had my IUD Skyla since late Oct 2016. Recently I have been experiencing almost all of the pregnancy symptoms (breast soreness/tenderness, nausea, fatigue, cramps, thick white discharge, frequent urination, problems having bowel movements) but all tests come up negative. I m also on a 30mg vyvanse prescription that I take almost everyday. What is going on with me?
