Needs some thoughts...

Rebecca
So my so and i started this month to become pregnant. I got lucky to start trying right after my period. It says my period is due in 4 day but i have no signs of it. I have been getting major heartburn for the last few days to where im eating tums like its candy...and some mornings if i dont eat right away I get very sick which normally is the other way( meaning if I eat breakfast i get sick). Ive also been an emotional wreck the past few days. Crying over stupid stuff lol. What do you think could i possibly be pregnant and when is a good time to test? Should I wait til after im late so i dont get my hopes up?
