I've got a little question :-)

Missy
Sooo... on July 9th I got what seemed to be my period ... it wasn't as heavy as normal but it wasn't as light as spotting ... about 12 days after I finished I started spotting for bout 3 days .... and I was supposed to get my period today but it never came how ever 3 days leading to today I started spotting just little brownish spotting ... as of today I'm 1 day late on my period .. is there a chance I'm pregnant or just over thinking .... the symptoms I've been having are .. exaughsted all the time .. hungry like I never feel full ... shortness of breath .. I was having heartburn for a few days about a week ago ... I'm having leg soreness especially inner thighs lately ... could you tell me if you have a clue what's going on my body is out of wack! Lol thank you so so much
