Too soon to fly?

Sam • I’m a mommy!

Got our BFP last week! Apps are predicting I am 5 wks. I have an apt tomorrow to confirm. I am worried because my dad is getting married in August and I may be around 17 wks and I have a flight to go back home and return in 5 days the flight is about 2 and a half hours. Is that too soon to fly?
