Around the day 3rd, I started noticing brown discharge. Then it got a lot heavier & lasted for around 4 days. When it was time for my period I didn't get the flow. It was just discharge & kind of colors all the time, for around 7 days. I usually get period for about 5 days though. & I don't think I'm feeling anything different than having a light cramps. Now I'm really stressed, is it normal or it has something to do with pregnancy?
