did my mother overstep her boundary??

I'm at my nieces 3rd birthday. My mom has been insensitive to me about my MC since it happened in August. I guess one of the super pregnant girls at the party mentioned to her how she did acupuncture to get pregnant. From across the room she yells "Jack she got pregnant using acupuncture! Why don't you try it? Nothing else seems to be working for you since you miscarried." I felt all the blood drain from my face. I smiled and nodded and at the first opportunity went to the garage and cried. I composed myself but I'm so hurt. I don't even think I can explain to her how she hurt me because she's never had a MC and she can't relate to me at all. Is it even worth it to tell her she hurt me? Or should I just let it go since she hasn't been able to relate so far, it'll prob just start a fight.... 😢
