Thanks for your query.
Your report is essentially normal.
However, the placenta should not be touching the os.
That indicates a low lying placenta right now.
In 90 % of cases, the placenta migrates upwards by the third trimester.
However a low lying placenta increases your risks of bleeding during pregnancy
, as well as miscarriage
However, a 2 hour flight should be fine as long as you get the relevant clearance from your obstetrician too.
