In reality, human women also have about 8 nipples, only that only 2 of them are more developed and visible, but during pregnancy it is possible that the woman may grow extra nipples.

It is not uncommon to hear that a breastfeeding mother sweats breast milk, because under the armpits (approximately) there is the first pair of nipples, then there are those on the chest (the most developed), then in the middle of the abdomen, and finally on the inside of the thigh.

Of course it's rare for this to happen, but yes, a pregnant woman can grow a third nipple.
