Writing from an airport...

I just started my second trimester. I was just assigned my third business trip of the month. It sucks because I usually travel about every other month but I know it will even out since I won't be traveling much third trimester and not at all on maternity leave.

Some coworkers are telling me I'm traveling too much. I don't think I am at this point yet but what is too much? Were you told by a doctor to limit air travel? I asked my doctor and she gave me a vague answer about trying not to travel too much and work too hard. I didn't find that very helpful.
