Hi everyone! I'm 21 years old. Im late on my period, I have very light brown discharge, and I'm not pregnant because I took a pregnancy test and it came back negative. I've been having this discharge for 5 days now. Last month I was late on my period 2 weeks also. And this month, in on hour, I will be late on my period for 2 weeks as well. Can someone help, please? I'm not sure what could this be. & it seems like some blood (3-4 drops) would come out only when I go to the bathroom.

Thanks everyone in advance.
