Are antidepressants taken while pregnant dangerous to the unborn child?
I've heard that from a friend that anti-depressants are a no-no during pregnancy as it increases the risk of autism in babies. Is it true? If so, then why do moms still take these while pregnant? Are there specific anti-depressants that are confirmed safe by practitioners? This is undeniably alarming.
