I am 21 and for the last two years I have experienced abnormal periods. Once my bf left to join the military my period became late every month, than I only had my period every 3 months and now I stoped getting it all together. I havent had a period for a few months. I only had my last period becouse the doctor put me on pills for 10 days to test my body. And I recieved my period from the pills. It was my first period in almost two years. since than it has been at least 4 months. and on the 4th of sept. my bf/ now husband left to go to iraq, I started spotting on my own. It only stayed at spotting and never got heavier. its brown and sometimes alittle pink. I dont need to use pads or tampons, its just not heavy enough. This was the first time in about 15 months that I started bleeding on my own and now it wont stop. what does this mean? I havent taken any pills or medication. And I have been with the same partner for almost 5 years so I dont think I have an std or anything like that. ?
