10 weeks, all symptoms gone since going on a 5 hour flight

Shannon
I am you 10 weeks today. 
I flew from the uk to cyprus at 9w & 5d. Before i flew i had all the usual pregnancy symptoms, nausea, vomiting, fatigue, sore breasts, keep needing the toilet etc. 
I absolutely hate flying so was nervous from the moment i got to the airport, i didnt move all the way, i was constantly dizzy and tried to sleep but couldnt. 
I am worried that by me being nervous i may have put stress on the baby and something may have happened. 
Has anyone else's symptoms lessened?
