Pregnancy related sickness?

Jess • Mama to a 1.5 year old boy after miscarriage🌈 pregnant with our second baby❤️

My stomach has been grumbling all day, I’ve been burping a lot, I feel starving even after I eat, and I’ve had a terrible headache. Just tonight I’ve also started feeling chills like I would if I had a cold or flu. Can these chills and aches be a symptom my little babe is bringing me? ..little worried
