Whether the amniotic fluid flows all the time or a little bit at a time is not a generalization, but needs to be combined with the specific time and condition.
In normal labor, the process of contractions to the full opening of the cervix takes about 12 hours for primiparous women and about 8 hours for transient women. When the membranes rupture, the amniotic fluid will also flow out, which is called water breaking.
The vagina of pregnant women will continue to flow more non-bloody liquid, when the fetal dew drops or fixed, amniotic fluid outflow will pause, until the fetus is fully delivered, the remaining amniotic fluid will continue to flow, so amniotic fluid outflow can be intermittent, but the position of the rupture of fetal membranes is relatively low, it may also appear that amniotic fluid has been flowing phenomenon.
If the amniotic fluid breaks in late pregnancy, you need to go to the hospital in time to avoid adverse effects.
