could I be pregnant

[LT420]

I had a MC September 20th. My next period was October 22nd and it last my normal 7days. Next period was November 20th and last 6 days. My next period wasn't due until the 19-20th of this month but it came 7-8 days early. It only lasted 2-3 days really light flow and the color was dark. My boobs has been sore and I have been feeling nause. I go to the rest room often than before. I took a HPT and it was negative. What could be going on? Is it possible I'm pregnant? Or could I have an off period? My periods are very heavy flow and this flow was really light and only 2-3 days vs my normal 7-8 days. Help

By the way I was pregnant. Last period was December 13th. Even though it was a really short, not normal cycle.  I guess all those symptoms were signs of me being pregnant.

Did you have unprotected sex?  A MC can mess things up.  If you are Bleeding 99% you are not prego.  I think you have nothing to worry about.  I know that my mind can make pregnancy symptoms happen asap.  And breast pain in a normal symptom for your period.  I know that my body will all of the sudden out of no where have a period with ALOT of boob pain when 80 % of the time I have no sore boobs at all.   I wouldn't stress,
