a couple of things: are you counting your period start date to start date? sometimes it's easy to get confused and not count from the first day pregnancy tests when used correctly are highly accurate sometimes you can totally psych yourself out and be super sensitive as far as what you are eating etc. when you are worried about something a pain in your side could be sooooooo many different things the only thing that will make you totally comfortable is to see your doctor but i hope this helps a little bit.
my period was 3 days early and lasted 3 days but my test were all negative could i be pregnant. i picked up an appetitie. also i've been having this cramp on the right side of my stomach. i took a test 2 weeks ago and it was negative. then i took another one lastnight and it also was negative. i came on my period october 3rd and it ended october 6th. on the 6th i was just spotting. i was originally supposed to come on my period october 6th.
