No pregnancy symptoms?

Shelia
Does anyone else not really have any pregnancy symptoms? Like I had some nausea the first couple of weeks, but not that I am 8 weeks along I don't really have any symptoms. No cravings, no morning sickness. I think the only symptom I really have is sore breasts. This is my second pregnancy and I know every pregnancy is different, but I've never heard of one where there aren't many symptoms.
