Title: Role in Emergent Cerclage of Indomethacin and Antibiotics
Brief Summary: Though cervical insufficiency is a common cause of second trimester pregnancy loss, the placement of an emergent cerclage in these patients is thought to improve perinatal outcomes. It is unknown whether the use of tocolytics and antibiotics prolongs pregnancies complicated by need for emergent cerclage.

The objective is to determine whether administration of peri-operative antibiotics and indomethacin to patients receiving emergent cerclages for cervical insufficiency increases latency period to delivery compared with patients receiving emergent cerclage alone.


Options:
A: Inclusion Criteria:

* Age from 20 - 35 years old.
* Pregnant from (12- 14 weeks) gestation.
* Singleton pregnancy.
* The pregnant women who have a history of second trimester pregnancy loss with painless cervical dilatation or have prior cerclage placement for cervical insufficiency or have a history of spontaneous preterm.

Exclusion Criteria:

* Multiple gestations.
* Congenital fetal malformation in the current pregnancy.
* Women with history of thromboembolism or bleeding disorders.
* Uncontrolled diabetes mellitus.
* Chromosomal abnormalities affecting one of the couples.
* Women refuse to participate in the study
* Antiphospholipid syndrome
B: Inclusion Criteria:

* GA 16+0 to 23+6 weeks
* Singleton gestation
* Presence of cervical dilation as diagnosed on digital examination
* Intact membranes

Exclusion Criteria:

* Age \<18 years
* Allergy to NSAIDs
* Renal disease
* Allergy to penicillins AND clindamycin
* Currently on antibiotics or indomethacin for any reason
* HIV positive
* Pregnancies complicated by fetal congenital anomalies
* Preterm premature rupture of membranes
* Fever of 100.4 degrees Fahrenheit or higher
* Any patient having received a therapeutic cerclage during the current pregnancy
C: Inclusion Criteria:

* women with history suggestive of cervical insufficiency together with ultrasound findings suggestive of cervical insufficiency undergoing elective cervical cerclage between the 11th and 12th gestational week.
* singelton viable fetus

Exclusion Criteria:

* women tested positive for bacterial vaginosis
* women currently with threatened abortion (vaginal bleeding or uterinecramps)
* age older than 35 years or younger than 20 years
* unwillingness to participate
* irregular and/or uncertain menstrual dates
* rupture of membranes
* previous cesarean delivery
* possible risks for preterm birth in the current or previous pregnancy such as twin pregnancy, IUFD, malpresentation, known fetal anomaly, progesterone or heparin treatment during the current pregnancy, hypertension, and/or seizure disorders.
* women with contra indications for cervical cerclage or anesthesia.
D: Inclusion Criteria:

* Documented history of previous singleton spontaneous birth
* Singleton pregnancy
* Gestational age at randomization between 16 and 22 weeks

Exclusion Criteria:

* Major fetal anomaly or demise
* Regular intake of fish oil supplements
* Daily use of nonsteroidal anti-inflammatory agents
* Allergy to fish or fish products
* Gluten intolerant
* Heparin use or known thrombophilia
* Hemophilia
* Planned termination
* Current hypertension or current use of antihypertensive medications
* Type D, F or R diabetes
* Maternal medical complications
* Current or planned cerclage
* Illicit drug or alcohol abuse during current pregnancy
