Health Information Pregnancy After Miscarriage

A high-risk obstetrician at Rush shares his insights.

Miscarriage is surprisingly common — in fact, some studies suggest that as many as 50 percent of pregnancies miscarry — but it's never easy.

Here, Xavier Pombar, DO, a high-risk obstetrician at Rush, talks about how he helps his patients navigate pregnancy after a miscarriage.

Q: How soon after a miscarriage is it OK to start trying to get pregnant again?

Pombar: Physically speaking, as long as there weren't any significant complications with the miscarriage, it's generally reasonable to start attempting to become pregnant again within two to three menstrual cycles.

Emotionally, it might be a different story. It's really up to the woman and her partner to decide when they're comfortable to try again. It's so personal that there's no right answer.

Q: Does having a miscarriage mean that a woman needs to fear subsequent pregnancy problems?

Pombar: For the overwhelming majority of women who miscarry before 10 weeks, subsequent pregnancies will be completely normal.

If a woman is young and has had one or two miscarriages, I don't recommend getting a medical workup or altering habits. Seventy percent of women who have up to three miscarriages go on to have normal pregnancies — so not only is a workup often a waste of time and money, it keeps a woman focused on miscarriage rather than on moving forward.

I've seen young women who were placed on medications like anticoagulants after one miscarriage when it really wasn't necessary. If you've had a miscarriage and have been put on medication immediately without thorough testing, you should definitely seek a second opinion.

Q: So you generally wait to test until after a woman's third miscarriage. What might you investigate at that point?

Pombar: After a woman has had three first-trimester losses (or two losses for women 40 and older whose reproductive window is shorter), we'll consider a few things:

  • Genetic or chromosomal abnormalities in one or both parents. For instance, a chromosomal translocation, a condition in which a piece of a chromosome has broken off and attached to another chromosome, can be carried by either parent.
  • An undiagnosed condition. One example is antiphospholipid antibody syndrome (commonly referred to as antiphospholipid syndrome or APS), an autoimmune disease that can cause abnormal clotting.
  • An existing condition, such as uncontrolled diabetes, that isn't being well managed. Women can improve their odds of a successful pregnancy significantly with pre-conception counseling and careful management during the pregnancy.

Q. Once you've pinpointed a likely cause of previous miscarriages, what can a patient expect while seeing you during her subsequent pregnancy?

Pombar: We will treat any medical problems we discover during testing. For many women, we'll also recommend extra visits to our office, earlier and more frequent ultrasounds, and antenatal testing such as fetal heart-rate monitoring.

But in a lot of cases, there's nothing special to do. Even so, I'll often make recommendations or offer reassurance based on my patient's previous experience with miscarriage.

For example, in pregnancy bleeding is common — up to 20 percent of women have some bleeding during pregnancy — but a woman who has miscarried might feel especially alarmed or guilty about it.

Also, exercise is not associated with miscarriages. But sometimes it can cause spotting, so I'll recommend that women take it easy while maintaining some level of activity.

Maintaining activity is key. In fact, I never prescribe bed rest. It doesn't work, and it puts women at risk for losing muscle mass, losing bone mass and developing deep-vein thrombosis (DVT), which can be very serious.

Q: The Internet is full of information — some reliable, some less so — about pregnancy after miscarriage. How do you talk with your patients about what's out there?

Pombar: I recently saw a T-shirt that I thought was great: "I don’t need a medical degree. I can Google."

Information obtained on the internet is a double-edged sword. If you know where to look, the Internet is full of useful information. I often use it for research myself, but I think I have a pretty decent filter. The problem is that anybody can put up a page, and once it's online it’s always there for someone to come across when they're doing research. Educating yourself is a good thing, but be sure to talk with your physician.

The bottom line is that it's so important to stay positive: We see many, many routine pregnancies and healthy babies for women after miscarriage.
