Preparing your body for pregnancy increases the chance of a healthy conception, pregnancy, baby and postpartum period. It is ideal to start optimizing your health three to four months prior to planned conception. This is due to the fact that it can take 90-115 days for sperm to generate and approximately 100 days for an egg to mature. It will also help ensure your body has all of the required nutrients to maintain your pregnancy with ease.
