Once a pregnant woman has decided to travel, a number of issues need to be considered before her departure.

An intrauterine pregnancy should be confirmed by a clinician and ectopic pregnancy excluded before beginning any travel.
Health insurance should provide coverage while abroad and during pregnancy. In addition, a supplemental travel insurance policy and a prepaid medical evacuation insurance policy should be obtained, although most may not cover pregnancy-related problems.
Check medical facilities at the destination. For a woman in the last trimester, medical facilities should be able to manage complications of pregnancy, toxemia, and cesarean sections.
Determine beforehand whether prenatal care will be required abroad and, if so, who will provide it. The pregnant traveler should also make sure prenatal visits requiring specific timing are not missed.
Determine, before traveling, whether blood is screened for HIV and hepatitis B at the destination. The pregnant traveler should also be advised to know her blood type, and Rh-negative pregnant women should receive the anti-D immune globulin (a plasma-derived product) prophylactically at about 28 weeks’ gestation. The immune globulin dose should be repeated after delivery if the infant is Rh positive.
General Recommendations for Travel
A pregnant woman should be advised to travel with at least one companion; she should also be advised that, during her pregnancy, her level of comfort may be adversely affected by traveling. Typical problems of pregnant travelers are the same as those experienced by any pregnant woman: fatigue, heartburn, indigestion, constipation, vaginal discharge, leg cramps, increased frequency of urination, and hemorrhoids. During travel, pregnant women can take preventive measures including avoidance of gas-producing food or drinks before scheduled flights (entrapped gases can expand at higher altitudes) and periodic movement of the legs (to decrease venous stasis). Pregnant women should always use seatbelts while seated, as air turbulence is not predictable and may cause significant trauma.

Signs and symptoms that indicate the need for immediate medical attention are vaginal bleeding, passing tissue or clots, abdominal pain or cramps, contractions, ruptured membranes, excessive leg swelling or pain, headaches, or visual problems.

Motor vehicle accidents are a major cause of morbidity and mortality for pregnant women. When available, safety belts should be fastened at the pelvic area. Lap and shoulder restraints are best; in most accidents, the fetus recovers quickly from the safety belt pressure. However, even after seemingly mild blunt trauma, a physician should be consulted.

Hepatitis E, which is not vaccine preventable, can be especially dangerous for pregnant women, for whom the case-fatality rate is 17%-33%. Therefore, pregnant women should be advised that the best preventive measures are to avoid potentially contaminated water and food, as with other enteric infections.

Scuba diving should be avoided in pregnancy because of the risk of decompression syndrome in the fetus.

It is especially important for pregnant women to adhere strictly to food and water precautions in developing countries because the consequences may be more severe than diarrhea and may have serious sequelae. Suspect drinking water should be boiled to avoid long-term use of iodine-containing purification systems. Iodine tablets can probably be used for travel up to several weeks, but congenital goiters have been reported in association with administration of iodine-containing drugs during pregnancy. Oral rehydration is the mainstay of therapy for travelers’ diarrhea. Bismuth subsalicylate compounds are contraindicated because of the theoretical risks of fetal bleeding from salicylates and teratogenicity from the bismuth. The combination of kaolin and pectin may be used, and loperamide should be used only when necessary. The antibiotic treatment of travelers’ diarrhea during pregnancy can be complicated. Azithromycin or an oral third-generation cephalosporin may be the best options for treatment if an antibiotic is needed.

Nowadays pregnancy rarely changes our schedules, with the exception of complications. Women continue their normal lives usually for the duration of the pregnancy, with minor exceptions (Like knowing where all the bathrooms are!). Travel is no exception.

Travel is becoming more prevalent as families move further and further away. Traveling for holidays or as a last trip to see the family before the baby or as a last romantic vacation, is not unusual. This even includes out of the country travel and often air travel.

Air travel has had it's share of bad stories told and rumors spread, add pregnancy to the mixture and you probably wouldn't believe the number of things that are said about air travel while pregnant.

Most of the studies on pregnancy and air travel have been done on female flight attendants. One study did show that there was a slight increase in first trimester miscarriage, but this was for the flight attendants who worked a greater number of hours.

Other studies were worried about in-flight radiation. This was also shown to have a slight increase in potential problems. However, these problems were more related to the length of time in the air, the route flown, and other flight phenomena.

While the first post in this thread resembles a cut and paste, travel for pregnant women is safer than it used to be.

At what point should pregnant women avoid any travel whatsoever?

well i know that its risky to travel but i guess an advice to a physician should be well noted..in my case i can still travel when i am one to seven months pregnant ..after that no more..pregnant women should be careful should she chooses to travel after seven months..
