In 60 seconds
Your short plan for this week
If pregnancy is possible, use pregnancy-safe habits now: skip alcohol, check medicines and take the prenatal supplement recommended by your doctor.
There is usually no routine appointment this early. Seek care sooner for severe pain, fainting or heavy bleeding.
Do not rely on a very early negative test as a final answer; repeat it after the missed period or follow the test instructions.
What you may notice
Your body and how you may feel
You may feel no different. If you are trying to conceive, continue pregnancy-safe habits without assuming a result.
What is happening
Baby’s development this week
Fertilization and implantation may occur around this stage, although pregnancy dating starts before conception.
Plain-language examples
What this means in real life
Example: week 3 is counted from the last period, so fertilization may only just have happened. It is normal not to feel pregnant.

Contact your care team
Contact your doctor or maternity team promptly
Some concerns need advice before the next routine appointment even when they do not feel like an emergency. If a symptom becomes severe, sudden or frightening, use urgent care instead.
