At about 3 months.... but it really is growing before then. The bigger the baby gets, the bigger your uterus gets. Its a slow process.

The zygote starts out as 2 cells. It experiences mitosis and turns into 4, then 8, 16, 32, 64, etc. During the first few weeks this change is not significant so the uterus does not expand quicky. Eventually, when 1 billion cells is multiplying into 2 billion cells, growth is quick and the uterus and placenta expand.

It depends on whether or not it's your first pregnancy.
During the second month, your uterus will begin to expand and, if this is your first pregnancy, it will be about as big as a tennis ball. With subsequent pregnancies, your uterus will become larger earlier in your pregnancy.

I think the Uterus can grow quicker if you're having multiples or in some cases if you've had previous pregnancies. I think it would take at least a couple months in either instance, though.

The uterus starts growing immediately. But you don't "show" until4 or 5 months because the uterus grows down first towards your bladder. that's why one of the first signs is having to pee all the time.

The uterus grows slowly along with the baby, so it starts right away.

A few months. You start gaining weight in the third month. It can make you bloated before then, though.
