Fighting

How often do you and your significant other fight? I'm 22 and my hubby is 24. We got married 2 1/2 years ago and have been ttc since we got married with no luck.. It seems like lately we fight all the time. We fight at least every other day it seems like. Idk what to do he says he's trying but it doesn't feel like it sometimes. We are both extremely stressed out right now with ttc and I have Crohn's disease and been really sick lately. I feel like I can't do anything right. Everyone in our church and family think we have a perfect marriage but I'm starting to feel like the stress of infertility is getting to both of us. Are we crazy or do you fight with your significant other just as much? When we first got married we like never fought ever. 😢😭idk what to do anymore.
