First month off birth control.

I ended my birth control last month and my last period was August 26-29. I have been feeling so funny the last week or so. Cramping, bloating, emotional, appetite. Just out of the ordinary. I took a test 2 days ago (9/12/15) and it was negative, but I figured it was to early to tell. So I tested again this morning and I swear I see the faintest line! I will test again in a day or so and see but what do you guys think? Is it possible?! I don't want to get too excited just yet but I can't stop thinking about it!
