I'm a FTM with twins. Both babies seem to be on the right side of my stomach, kinda like on top of each other. Is this normal? I'm just worried they won't have room to grow if they stay in that position. It may sound silly but I'm concerned they haven't spread out to the left side any. I'm going to the doctor tomorrow afternoon but this has been driving me crazy for a while now! Btw I'm 17 weeks.
