I have had hard sore swollen boobs since day 9 of my cycle... I really thought was pregnant but started bleeding today day 26.. my periods are never the same in any month ranging from 21-29 day cycles.. only ever lasting 2 days and always brown and sticky never red blood flow.. well no flow at all... apart from wondering why boobs so sore and why feel pg now worried my periods just aren't right,have read a few site this morning tryinng to find an answer and realised women get a flow red or other and only seem to get brown sticky at start/finish of a flow... still feel pg but took hpt on day 19 and today 26 day of cycle both negative,I think I might also ovulate very close to my period(brown sticky stuff)well what periods mean to me...
