From Amnio to Zygote, peep our glossary of all the pregnancy and birth-related terms you never knew existed, 'til now.

Secondary Infertility

/sek·uhn·der·ee· in·fur·tl·ity/

This refers to the inability to conceive or carry a pregnancy after you’ve successfully delivered a child. It’s fairly common and many couples resort to fertility treatments to carry another child, but if you have had one successful pregnancy, you’re more likely to have another. Maternal age (if you’re over 35), sperm count, weight and whether you drink or smoke in excess may be a factor in getting pregnant again.



Sudden unexpected infant death (SUID) or sudden infant death syndrome (SIDS) are terms used to describe the sudden and unexpected death of a baby less than one year old when the cause isn’t clear. These deaths often happen during sleep or in the baby’s sleep area which is why the American Academy of Pediatrics' (AAP) has updated its guidelines to suggest the safest ways to put your baby to sleep (on their backs) and maintain their sleepy safety. About 3,500 babies in the United States die suddenly and unexpectedly each year.

Slapped Cheek Syndrome/Fifth Disease

/slap·d· cheek· sin·drohm/

Slapped cheek syndrome (also called fifth disease or parvovirus B19) is a viral infection and common childhood illness. In children, it’s very contagious (spread through hand-to-hand contact and blood) and starts with cold-like symptoms followed by a rash. If you get infected with fifth disease during pregnancy, it usually doesn’t cause problems but you can pass it to your baby during pregnancy, which can cause miscarriage and stillbirth (this is rare). About half of all pregnant women are immune to fifth disease because they had it in the past.

Spina Bifida

/spahy·nuh· bif·id·uh/

Neural tube birth defects (malformations of the spine/spinal cord and brain and the tissues that enclose them) like spina bifida and anencephaly happen when a portion of the neural tube fails to develop or close properly, causing defects in the spinal cord and in the bones of the spine. Spina bifida can range from mild to severe, depending on the type of defect, size, location and complications and treatment depends on the level of severity.



The good news is that spotting is so super normal, especially within the first 12 weeks of pregnancy. It’s not usually a full on period, but generally lighter in flow and the color can range from pink to red and brown. Although it’s easy to get freaked out, do not panic! One cause of spotting could be implantation bleeding, when the fertilized egg attaches to the uterine lining. This spotting often happens before you even know you’re pregnant and most women confuse this with a period. Another totes harmless cause of spotting is a cervical polyp (a growth on the cervix), which is more likely to bleed due to higher estrogen levels. As usual mama, if you’re feeling like any bleeding might NOT be normal, please contact your healthcare provider. The more you know!

STD Testing

/es·tee·dee· test·ing/

A sexually transmitted disease or infection during pregnancy can pose serious health risks for you and your baby so you’ll be tested for HIV, hepatitis B and C, chlamydia, syphilis and gonorrhea even if you have been tested before. This will usually happen at the beginning and possibly at the end of the pregnancy. Be upfront with your doctor if you may have been exposed. The sooner it’s treated, the better.



A stillbirth is the death or loss of a baby before or during delivery, usually the term refers to babies lost after 20 weeks of pregnancy. Reasons for such a loss include issues with the placenta, umbilical cord, high blood pressure, infections, birth defects, medical complications for the mother and labor complications. Stillbirth affects about 1 in 100 pregnancies each year in the United States–about 24,000 babies.

Stretch Marks

/stretch· mahrk·s/

We prefer the term “Warrior Marks” or “Mama Marks.” After all, if you have stretch marks from pregnancy, why not rock them with pride?! But we get it. Sometimes you’re just trying to maintain that youthful, supple pre-preggo bod. Is that so wrong?! Of course not. The bad news is that in large part, stretch marks are hereditary, so if your mama had them with you, odds are you’ll carry on that genetic code. But some defenses exist in tackling stretch marks along the way.

One of the best stretch mark strategies is making sure your skin maintains maximum elasticity. You can achieve this by eating Vitamin-rich foods that help form collagen. Vitamin C in particular helps protect tissue from damage, while Riboflavin and Niacin are known to promote healthy skin. Also, drink at least 2 liters of water a day to help strengthen and renew skin.

In tandem with eating well, our best-selling Belly Oil is a nutrient-rich quick-dry oil that helps relieve itching + reduces the appearance of stretch marks. Its baby-safe botanical blend is formulated to support skin as it stretches + provides deep hydration without leaving a greasy feel. It’s a one-two, power packed hydration from the inside out AND outside in.



Gestational surrogacy helps those who are unable to have children become parents. It’s a process that requires medical and legal expertise because it’s not legal in 13 states, so you need to go through a lawyer to make sure the process is above board! Through IVF, embryos are created in a lab at a fertility clinic. Sometimes the intended parents use their own genetic material but sometimes, an egg or sperm donor is required. Then, 1-2 embryos are implanted into a gestational carrier, who carries the baby to term. Gestational carriers have no genetic relationship to the children they deliver and they are paid by the family for their services (along with their hospital bills).
