Oh my, being pregnant a second time around is so different. I found out 5 days ago. Have already gained weight (without ANY diet changes), significant amounts of nausea, dry heaving and OMG the cramping!!! (And I am not constipated). I know that every pregnancy is different.  But this is way different. I suddenly have a belly, something I didn't accumulate with my first until.... 18 weeks. I should only be 6 now. According to my last cycle and when I quit my birth control.
