Just two weeks after conception, your little one is a mere 1/100 of an inch long... that's roughly the width of three of the hairs from your head!
Here's a closer look at what your baby may look like right around two weeks after conception, or at four weeks menstrual age.

Now having been in existence for a month (since conception), your little one is about 1/6 of an inch long and has a head and a trunk. Limb buds -- early arms and legs -- are starting to be apparent.
A little baby face starts to take shape now: There are the beginnings of a mouth, and little divots that will become the ears and eyes begin to form.
No longer a flat disk, the sides of the embryo begin to fold along the long axis (a.k.a. the primitive groove or streak) and is three dimensional. The chest and stomach are forming, and the heart -- right now just a little tube -- starts beating around the 22nd to 25th day after conception. That wee heartbeat will be visible via ultrasound soon! Similarly, your baby's brain waves can now be measured with an electroencephalogram.
Here's a closer look at what your baby may look like right around four weeks after conception, or at six weeks menstrual age.

Your baby is now 1/3 of an inch long and weighs about one gram. Although he's tiny, little fingers and toes are beginning to form. An early tongue and twenty little baby teeth buds are in his mouth, and he now has nostrils.
Here's a closer look at what your baby may look like right around six weeks after conception, or at eight weeks menstrual age.
