Baby

Your baby is now the size of a peach, measuring just under 3 inches and weighing approximately a full ounce!

The most remarkable thing about week 13 is that his little body is finally starting to catch up to his head in size, as his head now only accounts for 1/3 of his total size. If you are having a girl, she will have more than 2 million eggs in her ovaries by week 13.

Her teeth are in place under her gums, waiting to come out during teething, which can start as early as three months, or as late as twelve months. (Note: Some babies can even have one or two teeth showing when they are born!)

Veins and organs are visible through your baby's skin, which is still paper thin and transparent. Her intestines are forming villi, which aid in peristaltic movement and digestion, and her pancreas has even begun to secrete insulin!

Mom

Congratulations, you made it to your second trimester! Good news -- You should be feeling better soon! The second trimester has a reputation for being the easiest and most comfortable trimester, some even consider it "The honeymoon period".

Your belly continues to grow, though you may still be too small for maternity clothes. Small bumps may become visible on your breasts. While these small bumps were always around, they become much more noticeable during pregnancy. They are actually an oil-producing gland called Montgomery's tubercles that help your body prepare for nursing.

Your expanding uterus can cause some discomfort or mild cramping. This is known as round ligament pain and it may feel like a short or brief stabbing pain along the side of your abdomen. Round ligament pain usually occurs when you shift positions quickly and usually subsides within a few minutes. Think of it as your body's way of reminding you to slow down! If you experience any pain that is concerning you, or if this pain is accompanied by other symptoms, like bleeding, omitting or cramping, contact your physician immediately.

With the first trimester behind you, its time to celebrate! Find a unique way to do something special for yourself. Chances are by week 13 your libido may be lifting a little thanks to hormonal changes and a decrease in symptoms like fatigue and/or morning sickness. Maybe some new lingerie for your increasing cup size is just the thing!
