Hey, this is my first pregnancy and i just hit my 10 week mark today. The passed few days i have lost my pregnancy symptoms. I didn't have much to begin with, no nausea, heart burn once, some uterus cramping, and a few head aches. But my breasts were very sensitive. Now the sensitivity has gone down and I'm getting nervous. I have my first doctor's appointment next week. Should i be concerned or is this normal for symptoms to come and go?
