baby bump or bloating?

So Im 15 weeks pregnant now and my belly is really starting to look bigger. Although, Im not sure if its baby or just bloating. I had Jaime take a picture of my belly last night. I will keep taking pics as the belly grows. I looked up other 15 week belly pictures online and it seems that most people just have a blubber belly at this point... which is what my belly seems to be right now. I cannot wait until it gets big and hard and I feel the little one kicking and moving!
