Your baby this week
Your baby is in trimester two with you! The fingerprints are forming — completely unique, one of a kind. The vocal cords are developing too. If your baby is a girl, the ovaries already hold over 2 million eggs — can you imagine? Your baby can suck a thumb now, and the bones are getting stronger every day. The body is finally starting to grow faster than that big head.
Your body this week
The second trimester is here! Many women start feeling much better — nausea eases, energy returns, and excitement builds. Your bump may start to show (every body is different). Increased blood flow might give you the famed 'pregnancy glow.' You may notice round ligament pain as stretching continues. Your appetite is likely returning with gusto. Enjoy this phase — many moms say it's their favorite.
