I started having a brown discharge about 6 days b4 my expected period thought it was just starting early but stopped after 3 days no regular flow ever started barley required a panty liner. My cervix is higher than normal belly feels tingly tired all the time and have been feeling light headed and dizzy. Some mild neasua at times but not enough to require a trip to the bathroom. I am 35 never been pregnant although we have been trying never taken any birth control and my cycle is very regular? Should I be concerned and what questions do you recommend asking?
