What "we" think is irrelevant, as it will have zero effect on whatever is really happening with your body. If you are truly concerned, go see a doctor and get a test from them. Doctors use pregnancy tests that are much better quality and more sensitive than what is sold for home use.
Your condition is not suggesting a pregnancy. If you want to confirm ,than go for a Serum HCG test. This test is confirmatory test.
Some time urine card/strip test may be false negative,because of less amount of HCG hormone in urine.
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.
