In December I got my period normal and on schedule. Usually every month it comes in the early to mid 20's of the month. January however, I came around 10-12 days early (so around the 10th of the month or so). It was a normal flow for me (pretty heavy, usual cramps) and lasted about 7 days, as it does sometimes. Now, it's the 30th of January and for the past 2 days I've been having light brown vaginal discharge. No weird consistency to it, just a light brown color when I wipe after using the restroom. Also, just starting today I began cramping. It feels like my period cramps that are in my lower abdomen, lower back and downward into my legs, really dull though and constant. However, I am NOT bleeding. I haven't had sex so I cannot be pregnant - I have 3 kids, I know what pregnancy feels like. I suspect I may have endometriosis, as my mother has it and I feel as though I have a lot of the symptoms. Any idea what this could be?
