How your baby is growing this week
Nothing visible yet. Week 1 starts from the first day of the last menstrual period — conception hasn't happened yet. Your body is preparing by thickening the uterine lining and selecting the follicle that will release this month's egg.
What your partner is going through
Menstrual period is happening or just ended. Estrogen is rising as a follicle matures. Most women don't feel any pregnancy symptoms yet — because technically, pregnancy hasn't started. This is the baseline week that doctors count from.
What to focus on this week, dad
- 01Start prenatal vitamins now — she needs at least 400 mcg folic acid daily, ideally 3 months before conception. You can take a men's fertility multivitamin too
- 02Review both your health insurance plans together — compare deductibles, OB coverage, hospital networks, and out-of-pocket maximums before you need them
