hi am 22 years old and my husband is 25.i mark my cycle down each month that way i know when it beganed and ended incase a doctor or hospital was to ask me.my cycle comes on the 18th and ends about the 21th.On October 15th i began to bleed but it was light and the blood was a light red compared to the dark red i usually have.so i figured i would wacth how many days it last and how light to heavy it would be.it lasted for 3 days and each day was light.i can compare the lightness to when your period is almost done and you only need use for a liner.i have been feeling symptoms but did not want to jump to conclusions but when i started bleeding lightly my mind started runing,it is now 10:55 pm october 18th and it has not shown up.when my period comes it usualy is light for a couple of hours and then goes into heavy mode and usally clots a bit and am not usually in a calm mood and i usually have headaches around my period and began to cramp and not want to move.so bascially am quiet curious on whats going on,oh and between those 3 days blood went from light to off about 2 or 3 times.can anyone help my confused mind?
