Sperm met egg, and voila — you've made a baby! Conception just happened a few days ago, so there probably hasn't been time for you to miss a period yet. If your little embryo has already made it to his new home, you may see a bit of spotting as the fertilized egg burrows into the wall of your uterus.

To-do:

Take a pregnancy test
Schedule first prenatal checkup
Tell your partner
Go to your checklist

[tip] Ask for a free sample of whatever prenatal vitamin your doctor recommends. Better figure out if you're able to keep one down before buying an enormous bottle.
