bloated vs pregnant

So, I have an IUD and I'm really careful when I have sex but I'm ALWAYS so nervous about accidentally getting pregnant. 
Well I had issues with eating for a long time and I've been doing so good now I eat like I'm supposed to but I've been extremely bloated and it scares me sometimes because I assume I look pregnant. Does anyone else feel that way? Like is it possible to look kinda pregnant when they're bloated?
