On August 13th I had my period and it lasted 4days that's it's usial. My cylcle is every 26 days. I bleed on the September 7th and 8th and then on 9th it was brown spotting. Since then I have been nauseous, urinating frequently, and tired, and cramping. I took pregnancy test at home and its negative. When should I test again? Or is it too early to tell.
