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.
It depends on how long hve u been pregnant. But mostly it's a week or less. If u keep bleeding after a week, and it's bright red, you should consult a doctor.
A very early one, yes.
If you suspect a miscarriage you have to see the doctor and he will examine you. If there is something left you will get infections.
