It is more than likely that Eve was taken from Adam after the sixth day. The clues can be gleaned from the Timeline:
Dry land Earth > Man fashioned + Gan Eden planted > Man borne to Gan Eden + Trees from the ground in Gan Eden > Man alone > living creatures as helpmate, from ground in Gan Eden > No suitable helpmate > Eve from Man in Gan Eden.
God made the dry land Earth on the third day.1 From that earth, he fashioned man on the sixth day.2 [And] the Lord God planted a garden in Eden, in the east, on the same day or _ day? The Lord God took the man and put him in the garden of Eden to till it and keep it on the same day or _ day.3 [And] from the ground in the garden of Eden, God made the trees from which man could eat from, the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil.4 This was on the _ day.
... some time elapses ...
After deciding to make a helper fit for him, God made from the ground in Eden, every living creature that Adam was later to name.5 This was on the _ day.
... some time elapses ...but for the man there was not found a helper fit for him. cf. [Gn 2:20]
Finally God takes Eve from Man on the _ day.
There isn't enough information to fill in the blanks and the timeline strongly indicates that Eve was taken out of Man, in Gan Eden, after the sixth day [Adam from dry land Earth].
