When you are seeking out pregnancy advice, it's always a good idea to really think about where the information is coming from and make judgements on how well it will apply to you.
You can get pregnancy advice from a great many different sources, from others who have gone through the process, from doctors, from Internet sources as well as from a variety of magazines and books.
When it comes to finding information on what you want, there will be no shortage of it. The problem you run into however is that not all the information out there is research or scientifically based and may not always be the safest for you to follow. For example, someone may tell you that they felt great when they ate a diet that was moderate in protein and fat and then lower in carbs while they prepared to give birth. This person could have had insulin sensitivity issues and that is why it worked so well for them. For you though, if you do not deal with this issue, it may not be the best approach for you to follow.
Likewise, while everyone may have good intensions when trying to help you, they do not know your body and how you will react. For any type of medical issue or something that definitely could play a strong role in your child's development, it's best to consult with your doctor. They will know your past history and will likely be able to give you better thoughts on what you should or should not be doing.
Furthermore, keep in mind that often experience is one of the best ways to learn. If it is something such as how you can reduce your levels of stress, look into your past and see what has worked before. Just because you are expecting doesn't mean any of that changes. You know yourself better than anyone so don't neglect to take that into consideration. Do what feels right to you because at the end of the day, that is really what matters.
Note though, obviously medical issues you do need to listen to professionals for safety's sake.
