okay , so I posted earlier this month about being 5 days late for my period well the day after I posted (6 days late ) I started to have light bleedin that was red but the next day it's was pinkish brown & by the end of the day it was just brownish discharge that lasted probably 3 days then nothing I usually bleed 6-8 days really heavy w/ blood clots bigger than quarters so this is weird the only other thing is bloating , headaches, tired , sick to stomache feeling , breast are extremely sore sometimes my nipples burn to touch my shirt & they have turned darker they don't feel bigger maybe a little heavy but that's about it . & increase in discharge my question is do you think it's implantation bleeding??af is due the first of December. am I out this month again??
