Teenage pregnancy is when a woman under 20 gets pregnant. It usually refers to teens between the ages of 15-19. But it can include girls as young as 10. It's also called teen pregnancy or adolescent pregnancy. 

CAUSES AND EFFECTS OF TEENAGE PREGNANCY

Causes:

• Drugs and alcohol
• Peer pressure
• Lack of knowledge
• Social media influence

Effects:

• Teenage births result in health consequences; children are more likely to be born pre-term, have lower birth weight, and higher neonatal mortality, while mothers experience greater rates of post-partum depression and are less likely to initiate breastfeeding.
• Depression: Being a teen mom is a risk factor for depression. If a mom has a baby before 37 weeks or experiences complications, depression risks can increase.
• These symptoms include mood swings, anxiety, sadness, overwhelm, difficulty concentrating, trouble eating, and difficulty sleeping.
