Baby this week
- •Sperm and egg have just met to form a single cell (zygote)
- •Cell division is beginning as the zygote travels toward the uterus
- •Genetic material from both parents is combining to determine baby's traits
You this week
- •You likely have no pregnancy symptoms yet—you may not even know you're pregnant
- •Some people experience light spotting or cramping as the fertilized egg implants
- •Typical menstrual cycle symptoms like breast tenderness or bloating may continue
This week's tips
- •If you're trying to conceive, take a prenatal vitamin with folic acid daily (400 mcg minimum)
- •Track your cycle or ovulation signs if you haven't already—this week is often when conception occurs
- •Avoid alcohol, smoking, and unnecessary medications, just in case
Informational only — always check with your doctor or midwife for advice specific to you and your baby.
Looking ahead
Next week, the fertilized egg will continue dividing and begin implanting into the uterine lining. Most people won't have any signs of pregnancy yet, so patience is key.
