Why on my period the first day or two I feel so faint and pale and horrible?

omg that almost exact thing happened to me today! i thought a shower would help but it made it worse!!! the only thing that helps me is laying down!!! i feel so bad for you because i really do know how you feel its like the worse thing ever and theres like nothing you can do but cry in pain!! well good luck :) and if you do find a better solution please let me know or i will let you know if i find one:)!!
