Am I the asshole for being upset?

TW: miscarriage

So I was at my cousin in-laws sons birthday party this weekend and she was yelling at everyone and started crying for seemingly no reason. She suddenly announced that she thought she was pregnant and asked me to take her to get a test. I said sure because she is my friend and I wanted to be supportive even though I get really depressed for a bit when people get pregnant. Not like I’m bitter, I’m still happy for them… I just have to take a sec to get over it.

So we’re in the car and she’s still talking about pregnancy and her first kid and I’m responding enough to not seem upset because at this point I’m not upset with her, it’s just a hard topic for me. I understand that she’s just excited and my feelings aren’t the first thing she’s thinking about right now obviously.

A few minutes into the convo however she says “You know that feeling when you get pregnant and you just know you’re pregnant? Oh wait you’ve never been pregnant” And she looks at my face and the look on it must’ve made her realize because she goes “oh nevermind I forgot you had a miscarriage” and continues on happily about what it feels like to be pregnant and how she was with her son. I was so hurt. She ended up not even being pregnant. I didn’t even know what to say so I didn’t say anything about it. But she knows how I feel because we’ve talked about my miscarriage before and my depression surrounding the topic of children. Am I wrong to feel hurt by this? I just can’t get over the way she said it and how she didn’t seem to care
