Is it normal to feel breathless easily

Yes normal :) I felt short of breath very easily especially after speaking a relatively long sentence from as early as 6-7 weeks, which never happened before. I found myself inhaling deeply more frequently between sentences during my conversations too (and still do now at 14 weeks!) Hormones are causing it + + the bloating contributes too + you’re now sharing your oxygen supply with your growing baby - demand has doubled! It’s normal unless you’re overtly significantly breathless or have any other respiratory symptoms.
