I'm still only 3w5d today and have been having tons of symptoms for a week now. I am on Prometrium, but I have always had unmistakable symptoms this early with all of my pgs and didn't have any symptoms the last two cycles I was on Prometrium.
My symptoms so far: heightened sense of smell (I agree, suzywan - SO GROSS!), weird taste in mouth, bleeding gums, extreme fatigue and irritability, clumsiness, tender breasts/letdown sensation (DS has been weaned since Oct.), vivid dreams (one about having twins!), frequent urination, increased appetite, bloated, nausea, and cramps.
If my past preganacies are any indication, most of these symptoms will calm down or go away in the next week or two and I'll have a little bit of a break before the morning sickness and food aversions kick in. Of course, the super-nose and fatigue won't go away for quite some time!
