Yes the very early miscarriages is something women might not notice.
You can miscarry before you even know your pregnant and just think it's a late period
Yes. Many women who miscarry that early never even know they had been pregnant.
If you are Five months pregnant and miscarry, yes, you would know. At that point a miscarry would be vary vary painful and bloody with removal of the fetus being necessary. Or it's possible that your doctor will notice the fact that the fetus has failed to thrive and terminate the pregnancy before the miscarriage takes place either way you would defiantly know.
The same way you throw up if you don't know you're sick. It doesn't matter.
Yes. Also, it may not actually be your first pregnancy. Very often women become pregnant and then miscarry before they even know that they're pregnant.
Yes, it is possible.
Yes, if your mother miscarries before getting pregnant with you the baby still counts as your deceased older sister or brother.
Considering boys can't get pregnant the answer is no. They have no fetus to miscarry.
yes. many miscarriages are missed b/c they miscarry before the woman even knew she was pregnant. the body doesn't like to bring messed up babies into the world, so if it is really messed up, it will miscarry
No not at all. You were lucky being able to get pregnant that quick.

You can miscarry as early as when you find out you are pregnant or earlier. I just had a miscarriage at 20 weeks, and I know several people that have had one later.
