A week ago I had a good scan at 6+6, baby with a heartbeat. At that point I had sore boobs but they were wearing off and had had some mild nausea but no sickness. I have now got nothing- breasts fine, occasional tiredness and that's it. Don't feel pregnant in the slightest. Should I be worried? Tell me your experiences positive and negative, I have another scan in a week and I'm really scared.
