On and off morning sickness??

Loredana

Hi ladies, this is my second pregnancy, I am 7 weeks and 2 days, at 6 weeks and 6 days I had my first ultrasound and saw baby heart beating at 115. My question is how many of you had morning sickness, fatigue, andsore boobs on and off troughout the early pregnancy, and is it normal? With my first I had morning sickness and sore breast for the first 4 to 5 months non stop. Si I'm not sure if this is normal or not...
