Blue fingers & swollen hands while flying

Has anyone experienced having blue fingers and swollen feet while pregnant and flying? I flew from Washington DC to Anchorage, Alaska yesterday. It was two flights and a total of 10 1/2 hours in the the air. My feet were so swollen that I couldn't fit them into my boots and fingers were so blue my husband was trying to rub them to see pink again during the last flight. Has anyone experienced this before? Going to do a check up when returning home in 10 days. But nervous for the flights home and how this little one is doing. Oh, and I'm 19 1/2 weeks along. I usually feel him moving around every night, but I don't tonight. I don't know if it's because it's early and he's moved, or I'm anxious.
