I just started my period.
Why is it so thick?
well...I have had some thick periods...some girls just have heavier ones than others...I dont think you have anything to worry about...however, if you have had sex and got pregnant, it could be a miscarriage...but I doubt it...dont worry about it. and if you're not already, getting on burth control should help lighten it up.
a lot of girls have think periods. Mine was especially heavy in the beginning. I won't worry about it, but if you are unusually tired and feel nauseous then go to your doctor and ask to test for an iron deficiency. Also if you want it regulated go on birth control.
its possible either the egg or egg bag
