EARLY pregnancy signs?

Lauren
Sooo I'm really trying not to get my hopes up to be disappointed in a couple days when aunt Flow comes (or doesn't who knows). All I know is I've been so tired, dizzy and cannot stop burping! For a couple weeks now... my boobs were pretty tender the last couple of days, not so much now. I'm about three days away from my period and we've been TTC for a year now. What were some of your early pregnancy signs? Am I reading too much into this?
