Question about period

Kelly
Well I had what I think/thought was my cycle the 15th. Well on the 14th I spotted but nor needing a pad. The 15th and 16th I had a pad and tampon on and bleed a medium flow on the 17th spotted not needing a pad and have had nothing since. My cycles usually last 4-5 days with heavy flow. Days leading up to my this my boobs were extremely sore, fatigue, nauseous. I still have been having these symptoms and nauseous everyday with vomiting. I took a test when I looked at 1st I didn't see anything went back and saw this what would you think. Test is after time frame. Thanks in advance.
