What do you guys think??

So i got my period this month on the 11th, Finished it on the 14th. Usually my periods are very heavy and the first two days are painful but this one was not as heavy and I barely had no cramps, Only light ones. So anyways, I have been having a couple of pregnancy symptoms so I decided to give it a shot and take a pregnancy test. I got a negative. Could it be too early? Or Am I just not pregnant?.
