The highest risk of miscarriage occurs in the very early weeks of pregnancy, specifically weeks 3 and 4. While the first trimester (weeks 1-12, sometimes extending to week 14) accounts for approximately 80% of all miscarriages, the risk is concentrated in those initial weeks.
Understanding Miscarriage Risk by Week
Several sources indicate a higher miscarriage rate in the first few weeks of pregnancy. While the overall risk of miscarriage decreases after 12 weeks, the probability is notably elevated during the first month post-conception.
-
Weeks 3-4: This period is frequently cited as having the highest miscarriage risk. Many women may not even realize they are pregnant yet at this stage.
-
Weeks 0-6: This broader timeframe encompasses the highest overall risk period. The chance of a miscarriage occurring during this period is significantly higher than in later stages.
-
Weeks 8-10: Some studies highlight weeks 8-10 as a period with a heightened risk.
The exact figures vary across different studies, but the overall trend remains consistent: the earlier in pregnancy, the higher the risk of miscarriage. It's crucial to remember that even with a higher risk in the early weeks, the vast majority of pregnancies progress to term without complications.
Important Note: This information pertains to the statistical likelihood of miscarriage. Individual experiences vary, and many factors influence the risk.
