What it is
NICHD says a pregnancy loss before 20 weeks goes by several names, including miscarriage, early pregnancy loss and spontaneous abortion.[2]
Sources differ
ACOG says early pregnancy loss happens in about 10 of every 100 known pregnancies, and about half are caused by an abnormal number of chromosomes.[1]
It is not your fault
ACOG says work, exercise, stress, arguments, sex, having taken birth control pills in the past and morning sickness do not cause miscarriage.[1]
ACOG says most women who have a miscarriage go on to have successful pregnancies.[1]
Signs
MedlinePlus lists these signs:[4]
- spotting or bleeding;[4]
- dark discharge;[4]
- a gush of fluid, or passing tissue;[4]
- cramping or low back pain.[4]
MedlinePlus says some people spot in early pregnancy and do not miscarry, but any bleeding should prompt a call to a provider.[4]
When to call
ACOG says to call your provider for spotting or bleeding, a gush of fluid or passing tissue, and to call right away for heavy bleeding or cramping like a period.[1]
After a loss, ACOG says to call right away for heavy bleeding, which it describes as soaking more than two maxi pads an hour for more than 2 hours in a row, or for fever, chills or severe pain.[1]
Support
ACOG names Share Pregnancy and Infant Loss Support as one support group.[1]
HRSA says the National Maternal Mental Health Hotline, 1-833-852-6262, takes calls and texts 24/7 in English and Spanish.[5]
