My symptoms started around week 5 this time around. I started off with just a BIT of queasiness (like really just a wave here or there). I was VERY tired, even before I knew I was pregnant. I'd go over to a friend's house to hang out and wake up 3 hours later on their couch, not even remembering falling asleep. By breasts have been sore since about 5 weeks. I have to pee all the time, though that didn't really kick in until about 6 weeks. I've been out of breath when I walk fast, or long, where I wouldn't have been before. I could smell EVERYTHING from about 4 weeks on.
I'm 7 weeks now, and the nausea is rearing its ugly head. I nearly tossed my cookies at my Dr. appt yesterday, and it totally hit me out of the blue. One moment I was completely fine - then I stood up and nearly lost my breakfast.
Every pregnancy for me has been totally different as far as symptoms and when they show up.
