If you are planning to conceive, a few months of preparation can support a healthier pregnancy. A prenatal vitamin with methylfolate is one of the most studied steps, ideally started before conception. Aim for steady blood sugar, regular movement, and good sleep. Track your cycle to learn your fertile window, and consider a preconception visit with your clinician to review any medications and health conditions. Reducing alcohol and quitting smoking are among the most powerful changes you can make.
