Before You Get Pregnant: Blood Work, Iron & Folic Acid

Here's the timing problem nobody explains: by the time a test shows two lines, your baby's neural tube - the structure that becomes the brain and spinal cord - is already developing. The window where folic acid matters most is largely over before most people know they're pregnant.

That's why the single most useful thing I did happened before conception: a doctor's visit and a round of blood work.

What to check

• Iron. Pregnancy pushes your blood volume up dramatically, and starting from a low baseline makes the fatigue much harder. Get your levels checked and corrected first.
• General vitamin and mineral levels. Anything low is far easier to fix before pregnancy than during it.

What to start

A daily prenatal with 400 mcg of folic acid, ideally at least a few months before trying. Folic acid is the one directly tied to preventing neural tube defects, and its critical window is those earliest weeks. Once I conceived, I switched to a prenatal with DHA for brain development, added iron to hit the daily target - and magnesium, because the iron was rough on my stomach.
