Galactocele while breastfeeding

A galactocele while breastfeeding is a milk-retention cyst caused by an obstructed duct, often felt as a painless breast lump.

Low milk supply

Supply runs on demand: the emptier your breasts, the faster your body makes more, so frequent effective milk removal is the main lever.

Mastitis while breastfeeding

Mastitis, a painful, red, swollen breast with a fever of 100.4 degrees Fahrenheit or higher, needs medical assessment, not a home fix.

Nipple pain while breastfeeding

Nipple pain is close to universal in the first week and eases for most people by around eight weeks, with latch problems the usual driver rather than yeast.

Nursing strike

A nursing strike is when a baby who has been breastfeeding well suddenly refuses the breast, most often starting around 5 months old.

HELLP syndrome

HELLP syndrome is a serious pregnancy complication involving red-blood-cell breakdown, elevated liver enzymes, and low platelets.

Oligohydramnios in pregnancy

Oligohydramnios means ultrasound found less amniotic fluid than expected. It can reflect ruptured membranes, placental insufficiency, reduced fetal urine.

Ectopic pregnancy symptoms most often appear around 6 to 10 weeks of pregnancy, especially as one-sided pelvic pain or vaginal bleeding.

High maternal serum AFP pregnancy screen

A high AFP pregnancy screen does not by itself confirm a fetal condition or cancer. The next step is usually to verify gestational dating.

Low PAPP-A in pregnancy

Low PAPP-A in pregnancy is a first-trimester blood-marker result, not a symptom or a prediction that something will go wrong.

NIPT low fetal fraction no result

An NIPT low fetal fraction no result means the laboratory could not issue a reliable screen, not that the screen was low risk or positive.

Positive NIPT result

A positive NIPT result means cell-free DNA screening found an increased chance of a chromosome condition, not that the fetus is confirmed to have it.

Choroid plexus cyst in pregnancy

A fetal choroid plexus cyst is a small fluid-filled ultrasound finding in tissue that makes cerebrospinal fluid, not evidence of brain damage.

Fetal echogenic bowel

Fetal echogenic bowel means the bowel looks as bright as bone on ultrasound. It can disappear.

Echogenic intracardiac focus

An echogenic intracardiac focus is a small bright spot seen in a fetal heart ventricle on ultrasound, not a structural heart defect.

Fetal pyelectasis

Fetal pyelectasis, now classified as urinary tract dilation, means the renal pelvis looks wider than expected for gestational age on fetal ultrasound.

Fetal ventriculomegaly

Fetal ventriculomegaly means a brain ventricle measures at least 10 mm on prenatal imaging.

Pemphigoid gestationis

Pemphigoid gestationis is a rare autoimmune pregnancy rash that often starts as intense itching.

Hives during pregnancy

Hives during pregnancy are itchy, raised wheals that usually move or fade within 24 hours, although new ones may keep appearing.
