Brief Summary:
First trimester miscarriages are common. When the failed pregnancy does not pass spontaneously on its own, it is called a missed abortion. There are several ways in which missed abortions are managed, one of which involves administering a medication called misoprostol which causes uterine contractions inducing expulsion of the failed pregnancy. Misoprostol can be administered in multiple ways but has been traditionally inserted vaginally when used for management of missed abortions. Some studies have shown that some women are not comfortable with vaginal insertion of misoprostol and prefer oral administration. Buccal misoprostol is a way of administering misoprostol by having the patients insert the tablets of misoprostol between their gum and cheek, letting it dissolve for 30 minutes, then swallowing the remaining remnants. Buccal misoprostol is used safely in medical abortion. In fact a study by Fjerstad et al (2009), found a decrease in infection rate for medical abortion when misoprostol administration was switched from vaginal to buccal route combined with routine administration of doxycycline. The efficacy of using buccal misoprostol to treat missed abortions has not been studied previously to the investigators' knowledge. In this pilot study, investigators aim to test the hypotheses that buccal misoprostol is equally effective as vaginal misoprostol in the medical management of early pregnancy loss. As secondary outcomes, investigators suspect that buccal misoprostol may be associated with higher rates of gastrointestinal side effect but that patient satisfaction will remain equally as high for buccal misoprostol as for vaginal misoprostol.

Primary Outcome Measures :
  1. Patient Enrollment [ Time Frame: One year ]
    The percentage of women who are offered enrollment and accept.

Secondary Outcome Measures :
  1. Number of Participants With Complete Abortion [ Time Frame: one week ]
    Number of participants with complete abortion without surgical intervention defined as no evidence of a gestational sac on transvaginal ultrasound at the follow up visit.

  2. Number of Participants Who Answered 1 or 2 on a Scale of Satisfaction With the Procedure [ Time Frame: one week ]

    Written surveys patients will fill out at follow up visit assessing patient's satisfaction with the procedure.

    "How satisfied were you with your procedure?"

    The satisfaction scale used was:

    1 =Very Satisfied, comfortable, likely to recommend 3= Neutral 5= Very unsatisfied/uncomfortable, unlike to recommend

  3. Number of Participants Reporting 2 or 3 on a Scale of Medication Side Effects [ Time Frame: one week ]

    Assessment of medication side effects including: nausea, vomiting, headache, fever (over 100.4 F), dizziness, diarrhea, bad taste, dry mouth "Did you experience any of these side effects? If so, how long did they last?"

    Patients asked on a scale of 0 to 3, where:

    Side Effect scale:

    0 = never

    1= less than one day 2 = 1 to 2 days 3 = more than 2 days
