We have been invited to go on a trip to the Eastern Sierras with family in July (would be pretty much free) but the cabin is at 9400ft. We would stay over night at 6000 ft on the way there to help acclimate. I would be about 15 weeks at that time. I live at maybe 700 ft, I have staged at 9800 ft before with no acclimation night before and was fine, but I wasn't pregnant. I'm not high risk in anyway, my research just says if you feel unwell at altitude rest and be sensible.
Has anyone travelled to high altitude while pregnant before?
