I'm 16 years old, i track my period because i have long cycles which are pretty easily thrown. 2017 i was fairly regular, but 2018 my cycle was all over the place due to a lot of stress and anxiety. throughout 2018 i noticed i would get very painful, sharp stabbing pains around the area my right ovary is, i told my mum and she said it was just ovulation pain but im not sure. i had the pain again right around ovulation and it lasted a whole evening and was achy and tingly throughout the night and into the next morning. the next day i noticed i had some brown discharge, thats a kinda regular thing for me, ive had brown discharge come up before mid cycle and its lasted 2-3 days and then gone away. i noticed this discharge on the 20th january, its now the 27th and im getting worried. the discharge is sticky and stretchy, a dark brown colour, pretty much resembles blood clots in a period. it smells kinda vinegary if that helps at all. on the 23rd and 26th i had a bit of blood too. there is no chance that its an sti or related to pregnancy because im not sexually active. it is light enough that it doesnt go through my underwear but heavy enough and thick enough that it makes a decent sized mark at the end of the day and sometimes is too thick to really soak in. it is worrying me but after my year of stress induced irregularities and this pain around my ovary i may be overthinking it.
