My sister is getting on my NERVES during pregnancy

So this happened yesterday and it is still on my mind about it happening. It is definitely a very minor incident but it isn’t the first time. My sister is a little over 5 years older than me, so people expected her to be pregnant first. Before I got pregnant, she NEVER talked about wanting kids or anything, but as soon as I became pregnant, all of the sudden, it is a major thing. Every single time she talks about anything pregnancy related, it is about her. It’s always, “When I get pregnant” or “When I have kids” She shows absolutely no interest in supporting me or my baby. She has also made a few comments on how I am not showing that much and I was VERY irritated at that comment as it made me feel like something was wrong with me or my baby.

Anyways, yesterday she made a comment saying she wants to get pregnant so badly just so she can have a bump. I get that comment, I do because it is definitely a plus in some situations. I absolutely love my belly. But I straight up told her that it isn’t always that simple and so many people glorify pregnancy. I am not saying it isn’t an amazing experience, it absolutely is and I love it. But people seem to not realize the negative side of things. I have had a pregnancy loss before, which was very traumatizing. Because of that, I have had severe anxiety during this pregnancy.

I don’t know, it just throws me off on how the only thing she talks to me about is her. I knew this was going to happen, I knew that when I got pregnant, she was going to magically want to be pregnant as well. This is also why I try not to tell her much information about baby things that I have learned because I don’t want her to have the easy way out. Maybe I am blowing things out of proportion??
