Do you need how late can you have an abortion in California? A woman may undergo an abortion in California up to 24 weeks into her pregnancy. Abortion is only permitted beyond 24 weeks if the woman's life or health is at risk. In certain situations, a medical expert must decide whether to conduct a late-term abortion, and the woman must provide her informed permission. Third-trimester abortions, often known as late-term abortions, are uncommon and are only carried out in situations of serious fetal abnormalities or circumstances that pose a life-threatening risk to the mother. It's crucial to remember that women in California have the legal right to receive abortion treatment and are entitled to make their own healthcare decisions.
