Your Pregnancy at Week 13

by Your Baby Club

Your baby now has it's 'bag for life'!

Week 13

your baby this week:

Wrapped around little one now, is a bag of protective waters - their amniotic fluid. This 'bag for life' is made up of two layers; the 'amnion' and the 'chorion'. This fluid filled sac provides a cushion for your growing baby.

As you would expect, your baby continues to grow rapidly in size and now has teeth, vocal cords, and even fingerprints!

Now you are feeling a little sprightlier, you may want to be more active, and get back to exercise if you have had a break. Take things slowly as you ease back into things. Things may start to feel a little different from a movement perspective as you get used to your changing sense of balance. As baby peeks above the pubic line, the pelvis is getting a little too cramped now.

your body:

Help is finally here! In the form of your perfectly grown placenta! Now you're in the second trimester, the newly grown placenta takes over the care and maintenance of your baby, as it busily provides your baby with all the nutrients and oxygen it needs. At the same time, the placenta takes away all the waste products that the baby doesn't need.

As a result, some of those pesky pregnancy symptoms may be taking a back seat and you get a little extra spring back in your step! You may be also getting a little extra growth around your waistline and your clothes may be starting to pinch just a little!

Don't forget - eating for two is an old wives' tale to be ignored. You will regret it later down the line if you put on lots of unnecessary weight, as baby only needs a maximum of 200 calories, mainly in the third trimester though, so look after yourself and keep treats to that all too boring minimum!

your tips & to do's:

If you've put off telling others about your good news, now is a great time. Sharing is caring! Encourage your partner/the father and other family members to get involved, but not beyond what you are comfortable with.

Develop a working budget, one that includes the costs associated with your new little addition. Of course, your budget will be influenced by your individual situation, such as your income and expenses, two incomes versus only one, and all other factors that come into play. Some costs to consider when determining your budget include health care (including hospital charges, doctor visits, prescriptions, and insurance costs), food (including breastfeeding necessities, formula and bottles, and baby food), and diapers. Your insurance will determine how much you pay for your prenatal care and delivery. Special circumstances, like bed rest, multiple births, or a NICU stay, may influence these costs. Talk with your insurance company to learn your individual co-pays and deductibles.

After childbirth, your new, little baby will see his or her pediatricians at least seven times during the first year for well-child visits. If you decide to breastfeed, you may want to rent or buy a breast pump, especially if you are returning to work. If you decide to formula feed, you'll be buying formula regularly. If your new, little baby suffers from acid reflux, allergies, or other special needs, they may require a special formula, which can cost significantly more. To determine estimate costs for diapers, remember the average newborn goes through ten to twelve diaper changes a day. Of course, there are other costs to be considered, but these are the major players. To prepare, save when you can and practice for maternity leave by living on one salary and set any extra earnings aside.

Enjoy your sex drive. The spike in your libido can provide health benefits to you and your little one, such as helping to improve your sleep and mood and speeding up your postpartum recovery with tighter pelvic floor muscles. However, you may need to go without acting on that loving feeling if you have a history of early labor or miscarriage. Talk to your midwife or doctor to determine what’s best for you.

your symptoms

If you're pregnant with twins, there's a chance your morning sickness and exhaustion will stick around for a while longer. For expectant moms carrying only one baby and experiencing a decrease in many of those first trimester symptoms, here's a list of some symptoms you can look forward to this week.

  • Increased energy
  • Increased mood
  • Increased sex drive
  • Visible veins
  • Round ligament pain
  • Nausea
  • Heartburn and/or indigestion
