In 1968, I briefly took dexadrine for weight loss (prescribed) by my doctor. After about a month on the meds, I found I was about one month pregnant and ceased the meds. My third son was born eight months later, a beautiful healthy baby. When he started school, I was told that he had Audio-visual Memory difficulties. He always had learning problems, but worked hard and finished two years of college. Could my medication during the first week of pregnancy have contributed to his difficulty? I have two older sons who have genius IQ. YYYY@YYYY
