yeh, i seriously have to see the doctor that abdomin thing is freaky hahah well i let you know what happens...ill prob see dr on monday or so ...
hylinda- yes I am 19 as well- similar symptoms- LET US KNOW WHAT HAPPENS!!!
I would say wait a week and retest if still negative and no period request a blood test from your doctor. I have never heard of one side of your abdomen being bigger then your right being a sign of early pregnancy. I'm petite as well (weighting 97lbs before I got pregnant) and although you would show faster the baby would be too small (the size of a poppy seed right now) to cause one side to be bigger. However bloating and headaches can be early pregnancy/pms symptoms.
