I found out I was pregnant last week on a work trip to the US. In the middle of the week when I was 4 1/2 wks I thought symptoms had started. Felt really awful with aching, tiredness, nausea, food aversions. But then towards the end of the week I felt a lot better and since being home I've been fine. Only have mild symptoms of sore/large boobs. Is it normal for symptoms to come and go like that or do you think I had some kind of bug? I'm now 5 1/2 wks and feel fine. Thanks for advice.
