Okay so last month in November I had two periods, one and the beginning and one and the end of the month. Each of these 5 days long. I wasn't sure when I was suppose to have my period again so I went online and did a period calculator it gave me December 26 on December 24 at 11 pm I started bleeding it was a medium flow! The next day it turned into a brownish discharge! By that night it was only coming off on the tissue when I wiped! Then it was gone by the 26th I usually stay on 4-5 days and even when I came off my mirena 5 months ago I still had regular periods? I'm having a little breast tenderness, I'm extremely tired all the time, my mood swings are killing my relationship, and my abdominal area just feels heavier! I don't want to sike myself out! I don't know when I should test! Please help?
