I have a 7 day period its heavy the first 5 days then gets lighter. Last month it started on the 9 and ended on the 13 some times it's 6 days but rarely. On the last day of last month I had a little bit of blood in like the morning but that was all. This month it started on the 13 and ended on the 17 and the first two days was almost a normal period for me but not as heavy like I wouldn't wake up to a puddle of blood on my pad. Then the last three days it was off and on brown and redish pink. I am feeling sick and headaches. Idk what's going on.
