don't wait after a miscarriage

I'll make this brief because it is 10pm on Friday night and Netflix is calling, but: please do not wait to try and get pregnant again after a miscarriage.  We've known for years that you are more fertile and less likely to have an adverse pregnancy outcome if you get pregnant soon (within 6 months ideally) of a miscarriage.  It's "old school" to tell women to wait a few months to get pregnant after a miscarriage, but this message is still being conveyed by some health care providers.  Women used to be told to wait mainly so we would know when their period was so we could date the pregnancy.  Since periods can often be a bit irregular for a cycle or two after a miscarriage, women would often be told to wait until they are back to normal to try and conceive.  If you are like me (and nearly every patient I've seen in the past 2 decades,) you know there really isn't a "normal" period, so don't wait for it.

We can now date pregnancies with ultrasound so there is no need to wait to thinking menstrual dating of the pregnancy is important.

A large analysis of over 1 million, yes 1 million, pregnancies was published this month and it confirms how important is it not to wait after a miscarriage to try and get pregnant.  This is, of course, assuming you are mentally and physicially able to try again.  If you get pregnant within 6 month of a miscarriage you are less likely to have:

  • another miscarriage
  • a preterm birth

 

You are more likely to have a healthy livebirth if you conceive within 6 months of a miscarriage.  So, while many women and couples need time to grieve a miscarriage, it is ideal if you can try to conceive sooner than later.
