Pink Spotting Need Advice

Ok, so im 19 have always had irregular periods.. Like every 4-5 months or something.. Last time i had my period was agesssss ago like 5 months or something. I was on the pill a little while ago to get rid of the cysts in my overies. But stopped because the pain went away, the doctor gets mad at me everytime i ask things about my cycle or down in there because he thinks i should be on the pill to regulate it, but i don't like the crazy/emotional/hormonal person it makes me. So unless i really need to, i'm not taking that route. Anywho so sometime around a month and a half ago for a week i was crazy emotional going out of my mind, hysterically crying every day, for some reason my monthly's never came to mind then i went to the bathroom one night and there was a little bit of pink blood on the toilet tissue, i felt so relieved that i knew why i had been acting so crazy because i dont get my period as much when i actually do its normally more severe(emotionally) and heavy. Then that was it nothing after that.. although this has never happened before i wasnt worried i thought it could just be because of stress or something. Then yesterday (like a month or a month and a half later) i felt a little cramp in my abdomen then next time i went to the bathroom i wiped pink again, this time i kinda had an idea that that's all that would happen, probably not my period coming on and i was right.. So i don't know why this could be happening all of a sudden and two months in a row. Also like 3 weeks ago i had the ITCHIEST nipples, could not find relief, scratching all the time, just so irritable and itchy for about 3-4 days i thought it could've possibly been because of the climate change though, because i was holidaying in bali at the time, increased appetite to the maximum but i think it could possibly be because i have recently stopped taking duromine while i went to bali and the reason i was on it was because of my unrelenting appetite. Im just trying to think of all the things that have been different in case they link somehow lol. hmmmmm aching hands, knuckles very painful. out of the blue pretty much. If someone just has any advice why i could have got the spotting two months in a row would be much appreciated. thank you [ Pink] [l]
