Hi my last period was oct 20th. Around Nov 7th I felt like I was on my period but I wasn't I did have brown disharge Oct. once when I wiped but that's it. Period was supposed to start the 17th and nothing no cramps nothing why?? I am 26 and have 3 kids. I don't think I am pregnant and I am not stressed. So what is going on? Any ideas or thought would help ease my mind. Thanks in advance.
