I'm currently 25 weeks into my pregnancy and have been lucky enough to have very few symptoms so far. However, this morning, without much warning, I was sick. It was just the once and I feel ok now, I think. I'm wondering what might have caused it. It definitely wasn't food-related as it had been too long since dinner & didn't have anything unusual for breakfast a short time before. I'm wondering whether it was a combination of being over tired (nothing to do with pregnancy, just not long enough spent in bed!), a bit stressed and the heat lately? Does anyone have any suggestions? It's another week until I see the midwife - I'll mention it to her then but I think a one-off episode like this probably isn't worth bothering her, or my doctor, with.
