Just checked using pregnancy test kit and its positive !. Its been 4 weeks since my last periods. Doctor is taking appointment only after 8 weeks and i need an advise. Actually I’ve plans to travel next week and its a long international flight of 20 hours. and then i plan to return after 8 weeks (would be total 13 weeks since last periods). Its an urgent travel and I feel normal with no nausea or anything significant till now other than little cramps or headache. Is it safe to travel. please advise.
