My period was a few days late and I was having pregnancy symptoms.. I just blew them off as pms symptoms. I spotted early in the morning on Monday, then it went away, so I took a hpt on Tuesday and got a faint positive, same thing Wednesday, and today (Thursday)  it was a little more visable than the previous tests. Then all of a sudden my period starts! It started out bright red, then went to a darker maroon/brown color. No clots as of yet, just seems like a normal period.. Slight cramping, but nothing terrible. What is going on? Chemical pregnancy maybe? My sister said when she had hers she had terrible cramping... So idk wether or not to take another test or just move on?! Help!!!
