How Do I Know If My Contacts Are Inside Out?

My doctor gave me new contacts – acuvue advance for astigmatism- because the ones I used before dried my eyes a lot. So the new ones are VERY soft and they roll all the time. The old ones weren’t as soft and i could tell whether they are inside out because their shape would change a little but these look the same on both sides. Can you give me any tips on how to recognize them? Thanx
