I'm not quite sure. Actually... I was looking for a similar question... But from what I've experienced with mine, you bleed. That seems to be the popular answer. Except... I saw... my miscarriaged baby. So I guess if you've seen it... you basically had one.
At 4 weeks pregnant, the fetus has just attached itself to your uterus. It is about 1/25 of an inch and less than 1 gram. Check out this website for a 3d picture!

I think it is similar to a heavy period.
like a microscopic grouping of cells
Your embryo will look like a blood clot.
Embryo
Nothing shows at 3 weeks.
they look like baby roosters
For a domestic hen the time is 3 weeks
My doc recommends at least 6 weeks and 3 days and even so it's early...Would try at 7-8 weeks
At 3 weeks it's a embryo, at 10 weeks it's a fetus and from week 38 or when it's born it's called a baby.Terminating your pregnancy is called an abortion.
If you ovulate around day 14 and have regular periods, by LMP (last menstrual period) you would be 5 weeks - the actual age of the embryo would be 3 weeks.
Of course not. You are not ovulating, no sperm can enter the uterus and there's already a embryo inside.
You wouldn't normally see a sac on ultrasound until about 5 weeks. Sounds normal.
The seed gets a tiny plumule and grows many radicles
5 weeks is the earliest most women get theirs (3 weeks after conception). They will have to do a vaginal ultrasound to be able to see anything and it won't look like a baby yet.
Your baby is actually starting to look like a baby at this point. It is approximately 3 inches long and between .18 ounces and .21 grams. Go here to view a 3D picture: http://3dpregnancy.parentsconnect.com/calendar/13-weeks-pregnant.html
