i am certainly no expert, but this is what i reckon.

CONGRATULATIONS!!!!!!!!!!!!!!!!

secondly, i think you can still do all of your current plans no worries. Flying only usually becomes an issue in the last stages of pg. i think the only thing that would stop you from carrying out your plans is if you have terrible m/s, goodluck with your pg and have heaps of fun in your travels, i am wishing you a very healthy and happy pg with absolutely no m/s.

About going to India whislt pg, i would just go to a GP and ask them what they think is best.

Also im pretty sure that you can still get your midwife at 5 months pg as thats only half way, still plenty of time to get to know a midwife
