When an ultrasound reveals that the embryo has stopped developing, the question of what to do about this pregnancy arises immediately. The body can sometimes handle this situation on its own, but not always, and medical options have evolved significantly in recent years. Understanding how the expulsion occurs, the signals to watch for, and the decisions to make with the care team allows one to approach this ordeal with more concrete references.
Incomplete expulsion: the risk that protocols aim to prevent
Most online resources describe expulsion as a linear process: bleeding, cramping, and then it’s over. The clinical reality is more nuanced. Incomplete expulsion of the gestational sac remains a central point of vigilance in recent French-speaking recommendations.

Specifically, this means that fragments of tissue may remain in the uterus after bleeding. These remnants increase the risk of infection or prolonged bleeding. This is precisely why medical teams never refer to natural expulsion as a guaranteed event without follow-up.
When seeking to naturally expel a deceased embryo, it is important to know that a follow-up ultrasound is systematically scheduled to ensure that the uterine cavity is indeed empty. Without this verification, a silent complication can set in.

Expectant management in a stopped pregnancy: waiting, but under supervision
Expectant management involves allowing the body to expel the tissues of the stopped pregnancy on its own. This approach is offered when the general condition allows it and when the term is early.
Wondering how this unfolds on a daily basis? After the diagnosis, returning home is now an explicit scenario in hospital protocols. The CHUV, for example, indicates that patients can go home unless a situation requires close monitoring.
What the body does during the wait
The uterus triggers contractions to expel the gestational sac. These contractions cause pain comparable to intense menstrual cramps, sometimes stronger. Bleeding varies from woman to woman, ranging from light to heavy, with the expulsion of clots.
Expulsion can take several days to several weeks after the diagnosis. This variable timeframe explains why some women prefer active management rather than waiting.
Warning signs to know
During this waiting period, certain signs should prompt quick medical contact:
- Bleeding that soaks more than one thick pad per hour for more than two consecutive hours
- Fever above 38 °C, which may indicate an ongoing infection
- Abdominal pain that does not subside despite taking standard pain relievers
- Malodorous vaginal discharge, a potential sign of uterine infection
Misoprostol and medical management of miscarriage
When spontaneous expulsion does not occur within a reasonable timeframe, or when the patient wishes to expedite the process, medical treatment comes into play. Misoprostol is the reference medication option to promote expulsion in a non-viable pregnancy.
This medication causes uterine contractions. It is administered under medical supervision, often on an outpatient basis. The effects typically manifest in the hours following administration: cramping, bleeding, and then expulsion of tissues.
Follow-up after medical treatment
A follow-up ultrasound is performed in the following days to confirm that the uterus has emptied completely. If expulsion remains incomplete despite misoprostol, an escalation to surgical management may be necessary. This stepwise progression (waiting, medication, surgery) is now the standard framework in French-speaking facilities.
Surgical treatment, by aspiration, is reserved for situations where the first two approaches have not sufficed or when the clinical condition requires it from the outset. It is a brief procedure, performed under anesthesia, with a return home on the same day in the majority of cases.
Stopped pregnancy and patient choice: what has changed
Current care pathways emphasize a point that was not obvious a few years ago: the patient participates in the choice of the expulsion method. The doctor presents the three options (expectant, medical, surgical) along with their respective constraints, and the decision is made together.
This choice depends on several concrete factors. The term of the pregnancy at the time of diagnosis plays a role: the more advanced the pregnancy, the longer the expectant approach alone may be or may prove insufficient. Emotional state also matters. Some women prefer the process to be quick so they can begin their grieving. Others need time.
Psychological support is not an extra
A stopped pregnancy affects a significant proportion of pregnancies. It is not a rare event, but the frequency does not diminish the pain felt. Care facilities now integrate a psychological component into the pathway, with referrals to professionals trained in perinatal grief.
A work stoppage may be prescribed. Its duration is tailored to the individual situation, with no imposed standard duration.
Regardless of the method chosen to manage the expulsion, medical follow-up remains the guiding thread. The post-expulsion follow-up ultrasound, monitoring for infectious signs, and emotional support form a triptych that recent protocols no longer dissociate. Choosing between waiting and active treatment is not choosing between a natural path and a medical path: it is choosing a pace, within a medical framework that remains present at every step.
