Pregnancy Symptoms...help!

KB
So I am currently 7.5 wks pregnant with my third! My last two pregnancy's were so easy, I had hardly any symptoms and really no complaints at all.
This one...not so much. I feel nauseous most of the day, it sometimes subsides when I eat but then I get an acidic stomach, I feel like my food is just sitting at the top of my stomach and I feel bloated...is this normal??
Has anyone else experienced this, does it get better after a certain point? I'm attributing this all to pregnancy because I've never felt this way before...I have taken tums, chewing mint gum... I've heard being sick means a healthy pregnancy but any advice would be awesome!
Thanks!
