Does this make me a bad person for feeling like this?

So... I just had to walk out in my in laws because my SIL made a non direct comment that she is pregnant with her second child. She tried to tell our other SIL like off to the side but I was sitting right there. I’ve been trying to have a baby for 3 and a half years with one miscarriage as my only thing to show. I just thought I would be the next one to get pregnant considering all the steps, medications, and appointments I go to. I think it hurts more as well because they can’t afford the one kid they already have. They skip meals because they can’t afford to eat but somehow found the money for a second baby I guess. When she was talking she said that she’s upset it ruined the rest of her year. My heart literally tore at that, I would give absolutely anything without question to get and stay pregnant. I’m having such a hard time understanding why my husband and I are struggling this much with having our first child while I’m being surrounded by people who can’t even handle their first one? I think I’ve just given up on trying to have a baby.
