See im 22 going to be 23 I have had bad gas, mood swings,heartburn, nausea, sometimes vomiting and im always tired im not on a b.c. i also have frequent urges to pee almost like i have a bladder infection and this is all been going on for about a month and a half. but both my home pregnancy tests i took said negative. whats up with that? I am going to a doctor on the 23 but it doesn't help me now.
