I had my morning sickness (mostly during night time) during my first trimester. It went away when I entered my second trimester. Now I’m at 30 weeks (third trimester) and my morning sickness appears to be back. I could not eat as freely as I did last trimester. Often having heartburn and vomiting series before bedtime. Is it common for morning sickness to be back when you enter third trimester? #firsttimemom
