Hi, 

im 34 years old. my cycle is 28-30 days. Last feb 2014, I thought I was pregnant because I haven't got my period for 40 days. It happened again this month, I got my period on the 45th day(last nov.7,2014). Now, I have this brownish color (like first day of menstruation). It's the 20th day of the cycle. Is this normal for my age? do I nedd to go to the doctor? Is this menaupausal stage already?
