Does water break at 4 months causing miscarriage?

No, water breaking, which is the rupture of the amniotic sac, does not typically occur at four months of pregnancy and is not a common cause of miscarriage. Miscarriages usually happen in the first trimester (before 12 weeks) and are often due to chromosomal abnormalities or underlying medical conditions. If you have any concerns about your pregnancy, it is important to consult with your healthcare provider.
