Yes it's normal it should get better after ur first trimester
One more thing is good to be on your feet in early pregnancy? And thank you
What you're feeling is normal with pregnancy. I had my first heartburn 2 weeks ago. I never had it with my first one. Just make sure your have meds for it. I use Prilosec and it works great for heartburns. If it gets really worse, let ypur OB know and you might have to have a prescribed medication for heartburns. You will notice that you start craving for foods that you normally avoid or don't like. It's ok yo be constantly on your feet when you're pregnant. If you feel dizzy or light headed, avoid abrupt movements
Normal take tums for the heartburn, stay away from foods that make you sick & listen to your cravings.
