Ok so I'm approximately 8 weeks pregnant. Everyone keeps telling me that I'm already showing and everyone keeps saying I'm going to have twins. This is my second pregnancy. Is it possible to show this soon with twins? Could i be pregnant with twins? I personally do not think I am showing, i think it's just bloat, but what do you all think?
