Blood group A individuals have the A antigen on the surface of their RBCs, and blood serum containing IgM antibodies against the B antigen. Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.
At some point, every pregnant woman wonders if it is safe to travel. The American College of Obstetrics and Gynecology (ACOG) suggests that the best time to travel is between the 14th and 28th weeks of pregnancy, or the second trimester. The mother-to-be is usually over her morning sickness and tiredness by then. It is also the time during the pregnancy when complications are least likely to occur. However, it is possible to be safe while traveling during the 34th week of pregnancy. Significance Traveling at week 34 and beyond is especially risky because it is very close to the motherâs due date--only six weeks away.
Motorcycle travel is not recommended during pregnancy. What if I am traveling by bus or train? You might have less opportunity to walk every couple of hours when you travel by bus. Take advantage of any stops the bus makes to get some exercise. When you are traveling by train, get up and walk every hour or two. Remember that there are fewer bathrooms on a bus than on a train. The motion of a train ride will not cause any problems with the pregnancy, such as starting labor. Are there special concerns for traveling by air? Flying is usually a safe way to travel. Most domestic airlines will allow a pregnant woman to fly up to the 36th week of pregnancy if there are no problems with the pregnancy. Each airline has policies regarding pregnancy and flying. Check with your airline when your reserve your tickets to see if you need to complete any medical forms.
