3 weeks.
Not necessarily. You can be clumsy and not be pregnant..
I've read that women can begin lactating as soon as 4-6 weeks into preg, however this is not common. Most woman say mabye a week before due-date or three days after birth.
No, but during early stages of being pregnant you can get bleeding which seems like a normal period. This is common.

if your period comes on early does that mean that you are not pregnant?
this will be seen near 7 month and being darker as further time passing on.
no it is not to early
No.
Yes. It can be a while before people know. It is very rare, but people have even been known to give birth without realising they were pregnant. Most know early on though.
When you start having cramp like symptoms but earlier then when your cycle is going to start this is usually an early symtom sign of being pregnant.
It varies based on your own body, we're all unique, but most of my friends started lactating in their third month of pregnancy. My sister didn't lactate until she was seven or eight months pregnant.
