Even though I found being pregnant to be a most enjoyable experience, I can also attest to the challenges that pregnancy presents. As each trimester unfolds in a pregnancy the body undergoes many dramatic changes including a heightened sensitivity to taste and smell, change in body shape, morning sickness, memory lapses as well as the inevitable emotional roller coaster ride. Essential oils can play a significant role in balancing the ups and downs and bring some pleasure to what should be the most rewarding time of a woman's life.
