Ok so I'm currently on my third period within a 6 week period and the symptoms I exhibited before this current period started are concerning as well as the timing of the periods. So before this period started, two days before I had light spotting of brown discharge, just a few drops. As well, I had begun to feel extremely weak and could barely stand or focus on anything, I couldn't even get up to cat until I regained strength to do such. There was also light pain but not much, I would consider it tender for about 5 minutes but that's it. Then the next day I wasn't weak or in pain but I had more light spotting of brown discharge but with more drops. Then today I started my period in the morning and I hadn't noticed yet since I hadn't used the restroom but I had begun to feel a burning sensation and my crotch began to smell of hot sauce for half an hour (the burning lasted for a few hours) before the smell changed to how it normally smells when I begin my period. The burning had stopped once I got into a new change of underwear and a pad. I have also only had slight pain in my side but like before, I would only describe it as tender. Do you all have any idea what is happening? Also if you need this information I am 16 years old (17 in a month)
