I wonder if I'm having twins.. I'm going to do a sonogram this Saturday with my Hubby! Did anyone here give birth to twins? If so, how did you tell that you were having twins? what are the early signs? because I think I'm showing at 9 weeks, and I'm always tired, and get worn out pretty fast... It could just be that I'm fat and weak, but my beach bods already gone. Is this psychological, or do you think I'm actually having twins? My mom thinks I'm having twins.
