What is a threatened miscarriage?
Any time there is vaginal bleeding during early pregnancy, or the first trimester, it is considered a threatened miscarriage. This bleeding may or may not occur with cramping. Most of these pregnancies result in a full term pregnancy with less than 30% ending in a miscarriage.
Bleeding and pain that happen during threatened miscarriage are usually mild and the cervical OS remains closed. Most women do not pass tissue during a threatened miscarriage. You may have some pain and tenderness in the abdomen when you have a threatened miscarriage.
Up to 20% of pregnant women will experience some vaginal bleeding during their first trimester. Be sure and consult with your doctor or midwife if you have any vaginal bleeding during your pregnancy.
