I had a period in late October (Oct.22) and then completely missed November's period. I started experiencing a few pregnancy symptoms. Fatigue, nausea and dizziness. I took 4 tests and they were negative. I then started my period for December 8 days early, still had pregnancy symptoms. It was very painful and heavy the last two days (lasted only 4 days). And now 5 days after my period I'm still having the period symptoms, added are cramping, headaches, hot flashes and very tender breasts. Iv taken 4 more tests and they're also negative. What in the world is going on? I already have two children ages 2 and 9 months.
