From what I have read, I don't believe you could be pregnant, but. There is a great book I read about that certain topic in it, I think its called girl stuff, going by your age, 20.. you have had your periodn for a few years? Becuse for the first two years or so, that seems to happen a lot.
Did to me. Sorry if I am of no help, but, I am just saying what I know, with the hope of helping in some way :p.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
