I'm 15 weeks and haven't travelled yet, but yesterday we had a 6 am flight, so up at 4 am, then lots of walking through airports and driving. Then we spent the day going out to eat and sightseeing..... I got to the afternoon and I felt a few cramps. Mild, just there. And just kind of achey in my uterus when I moved around and walked. It kind of hurt to bend over. Felt great when I sat. I drank loads of water but does this sound normal? I slept great last night and feel good today, but want to be reassured if it happens again today --we are off to the zoo. Does this sound like normal pregnancy discomfort?
