When you become pregnant your baby begins living and growing at the moment the father's sperm joins with your fertile egg. Thats called conception.
Eighteen days after conception, your baby's heart starts beating.
By thirty-five days after conception, your baby has a brain, eyes, ears, mouth, and more.
Seventy days after conception, your baby already has fingers, and also fingerprints. In fact he or she can make a fist to hold onto an object.

Suck on his or her thumb.
Recognize your voice.
Stretch and even get the hiccups.
