Safe medications before conception

Safe medications before conception

Alcohol and preconception health

Alcohol and preconception health

Why alcohol matters before pregnancy begins Preconception health is not limited to the day a pregnancy test turns positive. For many people, the preconception period starts well before that moment, because ovulation, fertilization, and implantation can occur before pregnancy is recognized. That timing matters: alcohol can affect the embryo during a phase when cells are […]

Quitting smoking before pregnancy

Why quitting before conception matters Smoking affects pregnancy before many people know they are pregnant. In the first weeks after conception, the embryo implants and the placenta begins to form.

Healthy BMI for conception

Healthy BMI for conception

What BMI tells us before conception Body mass index is calculated from weight and height and is used as a quick population-level estimate of weight status. In fertility care, it helps clinicians identify people who may have higher or lower chances of ovulation-related problems or pregnancy complications linked to weight. The important limitation is that […]

Blood tests before pregnancy

A clinician looks at your medical history, prior test results, vaccination records, menstrual history, medications, family history, and whether you have had […]
