If you smoked three blunts in the first months of your pregnancy will weed harm unborn?

There is no safe amount of marijuana that can be used during pregnancy. The American College of Obstetricians and Gynecologists (ACOG) recommends that women not use marijuana at all during pregnancy. Marijuana contains chemicals that can cross the placenta and reach the developing fetus. These chemicals can harm the fetus, and smoking marijuana has been linked to problems such as:

Low birth weight. Babies born to mothers who smoked marijuana during pregnancy tend to be smaller than babies born to mothers who did not smoke marijuana.

Brain development problems. Marijuana can affect the development of the baby's brain, leading to problems with memory, attention, and behavior.

Addiction. Babies born to mothers who smoked marijuana during pregnancy are more likely to develop an addiction to marijuana or other drugs later in life.

Respiratory problems. Marijuana smoke can irritate the baby's airways, leading to problems such as bronchitis and pneumonia.

Overall, marijuana is a risk to the developing fetus, and women should not use marijuana at all during pregnancy. For more information on the effects of marijuana during pregnancy, you can talk to your doctor or an addiction specialist.
