Weirdest belly button... I feel alone! :/

Melodie • Baby #1 is 18 months... TTC#1= PREG at my second round of clomid. Now PREG with baby #2. First month we tried, no medication. Due date= nov.2018 ❤️ PCOS+MTHFR+FVLeiden homozygous. 11 years with my husband. 28M-28F
I know I shouldn't be worried about that...but I still am. My belly button is so stretched out and the skin is really thin around it. Not really cute. Am I the only one, is it normal? All my friends have beautiful bellies while preg and I feel alone with my creepy belly button. Do you know if it will ever go back to (almost) normal after pregnancy? FTM, 38w1d.
