I have a regular cycle each month normally between 21-23 days apart. My cycle lasts between 3-4 days apart. Having said this, it is time for me to have started and I have had all the symptoms of my on coming cycle, the cramps, cravings, moodiness, but I have not started bleeding. I have had a brownish discharge and had a little bit of a red discharge just before my cycle should have started after having sex with my husband. What could this mean?
