There are three trimesters. The first trimester is the first stage of pregnancy from conception to 12 weeks The second trimester is the 13th week to the 28th week The third trimester is from the 28th week to the birth of the baby.
Traveling during the 5th week of pregnancy has to be determined by your doctor. A doctor's will know your health and give you the right advice.
How could you possibly know your pregnant if your only 1 week along
Many pregnancy tests can ascertain pregnancy within the first week. If you believe yourself to possibly be within the second week, you could take a pregnancy test now.
