Am I wrong?

My family has a group text, my sisters, cousins, mom, aunt etc. Last night they were posting silly selfies and then my cousin starts in about how she wants to lose weight before trying for baby #2, then my sister replies that she can’t be pregnant in September because that’s when they’re going to Disney. Then my cousin continues talking like she won’t start trying til then because she wants to be cute and skinny this summer.

The reason this bothers me is that I’ve been trying to get pregnant unsuccessfully for over 2 years, and I felt it was a little insensitive to say all that, especially when it could have been a private text. And she only took 3 months to have her first and all the other women in my family conceive super fast. Maybe I’m taking it too hard, idk. But I know if I said anything about it they would get super defensive. I guess I should just let it go.
