my last period was july 24,2012 and it skipped right through august and september is almost over and nothing yet.

i feel realy bloaded and am gassy, increase of appetite, and feel like vomiting but then it goes away, and my stomach has increased on the lower part and have mood swings. Though i have taken 2 pregnency tests and they both came out negative but its still not convinced me. lately i've been having dreams of a small child. Though i dont know if im pregnant or not and everybody keeps asking me if im pregnant so please tell me what u think...
