Hi I have been diagnosed wid low lying placenta grade1, I wanted to ask if I can travel by plane in my 18 th week on 2 hours flight vid grade 1, is it risky.. I asked my doc she said u don't have to exert plane travel is fine Bt no exertions it cud cause bleeding... I ll be in the resort n no exertion but is it safe to fly... It's my first preg so quiet tensed. Plz suggest
