i've only had a normal period since april (about 4 months). before then it would only come about every 3 or 4 months and only stay for about 4 days, sometimes less. now it comes every month and stays for 5 to 7 days. i have about a 30 day cycle. but this month it was a week late and lasted for only 1 day. it came monday night, lasted all day tuesday, and today i noticed when i went to the bathroom (i hope you dont get grossed out) a small glob of thick brownish redish blood came out and i havent bled all day since. i took a pregnancy test 4 days ago and it came up negative, so i dont know what else it could be. i want to think its just because i dont have a history of normal periods and its just messing with me, but i want to make sure. any help would be appreciated.
