Your baby at 20 weeks
Your baby is covered in vernix, a white, greasy coating that helps protect the skin.
They're getting more active: kicking, punching, turning and maybe sucking a thumb.
Your body at 20 weeks
You're halfway there.
Cramp in your calves at night is common. Rub the muscle hard or pull your toes up towards your ankle.
Halfway! Mark it with something small and lovely, even if it's just cake.
Your to-do list at 20 weeks

If you’re trying to conceive (TTC), you probably know that there are certain foods and nutrients that become especially important once you’re pregnant. But nutrition plays a vital role even when trying to conceive, much like laying a strong foundation before constructing a house.
Certain nutrients create that foundation by supporting egg and sperm health (yes, nutrition matters for both partners), hormone balance and creating a hospitable environment for a fertilized egg to implant. In fact, studies show that certain nutrients can help increase fertility and improve success rates for both natural conception and fertility treatments.
In other words, nutrition is a key player in the TTC journey, but getting the right nutrients in the right quantities can be tricky. That’s where supplements come in. Just as you’d take a multivitamin to fill in nutritional gaps for optimal health, fertility supplements can give you that extra nutrient boost.
