    Baby this week

    • Sperm and egg have just united to form a zygote
    • Cell division is beginning (blastocyst stage)
    • The fertilized egg is traveling toward the uterus
    • Genetic material from both parents is combining

    You this week

    • No noticeable symptoms yet—you may not even know you're pregnant
    • Possible mild cramping as the fertilized egg travels
    • Typical menstrual cycle symptoms if pregnancy hasn't been confirmed

    This week's tips

    • Continue taking prenatal vitamins with folic acid if you're trying to conceive
    • Avoid smoking, alcohol, and recreational drugs
    • Maintain a healthy lifestyle with balanced nutrition and gentle movement
    • Try to manage stress through relaxation techniques you enjoy

    Looking ahead

    By next week, the blastocyst will implant in your uterine lining, and your body will begin producing pregnancy hormones. This is when you might start noticing early pregnancy signs.
