Thanks for your question.
A low lying placenta is quite common at this gestation. This is good that you don't have any history of bleeding. It is generally advised that you must avoid trauma, jerks, prolong exertion & sexual intercourse till your placenta migrates higher up. If you have to travel due to personal reasons then try to postpone your visit till the 12 completed weeks. As second trimester is usually the safest period to travel or you can wait till your placenta migrates. Try to avoid fatigue
as much as possible on the way back home.
Best of luck.
