Am I Pregnant or just imagine it?

Alright well i took a pregnacy test well two of them the first one said i wasnt the second one i took a couple days later and it was positive then the line faded away a couple mintues later. i have benn going to the bathroom more then i do normally i have benn eating alot more but now when i want something i go get it and then i lose my appetite and cant eat it. i go to see alot earlier then i usally do and my stomach feels bubbly but not how it does when your about to get your period like bubbles popping in my stomach is that what happens when your pregnant like is that normal? and after i took my HPTs i was bleedin but not like a regular period and it didnt last as long as my period normally lasts it only lasted about 2 days...im unsure if i am or not does anybody no if i could be like does it sound like i am?
