Real Food for Pregnancy: The Science and Wisdom of Optimal Prenatal Nutrition

You can head off preeclampsia via food/supplements -- I'd highly suggest the book Real Food for Pregnancy! They have a section on this topic.

Do you have regular periods & ovulation? Are you charting your fertility markers with a Fertility Awareness Method? This will help to really get to know your cycle and see if & when you're ovulating. You can confirm ovulation and measure the length of your luteal phase via basal body temping every day, and cervical fluid tells you when ovulation is approaching. As someone else mentioned, the book "Taking Charge of Your Fertility" is pretty lifechanging for learning about all of this. No reason not to start gathering these data points now! There is also a whole world of preconception prep out there -- the book Real Food for Pregnancy is absolutely amazing and aligns so well with info about some of the nutrients that female runners often end up depleted in. The Fertility Friday podcast also has tons of excellent episodes on preconception prep! There are also lots of basics you could get checked now via bloodwork -- vitamins/minerals, thyroid, hormones.
