The following may be signs of miscarriage:

  • Severe abdominal cramps and abnormal spotting or bleeding;

  • What appears to be late (or not) menstruation.

In cases where a miscarriage is diagnosed further into the pregnancy, a dilation and curettage (also known as a D&C) may be necessary.

No matter at what stage of the pregnancy it takes place, miscarriage can be accompanied by feelings of disbelief, guilt, or psychological distress. It is therefore important to seek out psychological support to get through this ordeal.

Here are some organizations who offer aid to people who are bereaved following a miscarriage (French only):

It’s estimated that 12-15% of pregnancies advanced enough to be medically recognized end in miscarriage. It’s therefore important to consider miscarriage as a possibility while trying to conceive.

The causes of miscarriage are principally:

  • 15% endocrine issues

  • 5% genetic issues

  • 15% auto-immune issues

  • 20% anatomical issues

  • 45% unknown

Detecting Pregnancy or Miscarriage With The Sympto-Thermal Method

With the Symptothermal Method, it’s possible to detect a pregnancy well before it’s medically confirmed. It’s also possible to identify a miscarriage in the case of bleeding during early pregnancy. 

Women who are pregnant will often observe a second thermal shift around one week after the first shift that happens at ovulation. This second thermal shift leads to a third plateau, nicknamed the “pregnancy plateau”, and is a sign that pregnancy has probably commenced. It’s after 20 days of high temperatures (which includes both the second and third temperature plateaus) that pregnancy can be confirmed. 

In the case of abdominal pain or bleeding during early pregnancy, miscarriage is confirmed if the high, third plateau temperature drops back down to the low pre-ovulatory temperature levels of the follicular phase. But if the temperatures remain in the range of the third plateau, this is a sign that the pregnancy is continuing.

We suggest resuming symptothermal charting immediately after a miscarriage, as fertility can return quickly.
