Hello, I am 20 weeks pregnant and yesterday my Doc said that I have low placenta, we have a honeymoon in two weeks and trip by air is planned (1 hour and then 3 hours) . Please advise if its safe to take plance or better to cancel ? My doc told that its ok, I can take plane, but no heave stuff to carry and no sex, no swimming in the sea, not setting a lot on a sun. Please advise.
