Three pregnancy losses? Two? The number that defines recurrent miscarriage depends entirely on which guideline you are reading.
If you have had more than one pregnancy losses, you may have searched for a straightforward definition of recurrent miscarriage and found three different answers instead.
The UK's RCOG says three or more pregnancy losses. Europe's ESHRE says two. The USA's ASRM also says two.
None of these bodies is wrong. They are answering slightly different clinical questions, and the difference matters because it shapes when investigation should start.
What all three now agree on: pregnancy losses do not need to be consecutive, and for RCOG, they do not need to be with the same partner, to count towards your total.
Whether you have had one pregnancy loss, two, or three, there is a sensible next step for you. In around half of cases, no clear cause is found, and even then, the outlook with supportive care alone is genuinely good.
At JIVA Fertility, we offer a thorough evaluation to understand the potential causes of recurrent Miscarriage, and based on your circumstances, we may recommend diagnostic tests and discuss and agree a management plan for a successful future pregnancy.
