Random things

I've never had heart burn or indigestion, what ever it is that I'm feeling, before recently. Now it's been happening for 4ish days and today I'm feeling a bit ill... not enough like I feel like I'll be sick, but just kinda off. I'm also consuming waaaay more water than I normally do. Yesterday I didn't think about it because I was at work, but there was at least 8 bottles there. Then I polished off half a bottle with dinner. Right before bed was a full bottle, and right when I woke up was another bottle. Now I'm at work again and on bottle 3 and I've only been here 3 hours....

I don't know how early people start feeling symptoms of pregnancy, I don't even know what all this is I'm feeling but any information would be very welcome.
