Those are all signs of pregnancy, but nothing is a sure sign of pregnancy but a positive test. Some women will have light spotting when there period is due and if they are not trying to get pregnant won't think anything of it other then it was light this month. If you had a bright red flow, that followed the usual patten of a period (light, heavy,light) then more then likely you are not.
But if it was light, then it could be implantation bleeding. The only way to know for sure is to test.
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.
