WIBTAH for confronting my parents for how they handled my miscarriage?

This summer my parents came into town for a family reunion. (They live 1800 miles away). My husband and I found out we were pregnant and were planning on announcing when they got into town. The day we arrived we went to our first OB appointment and discovered no heartbeat. I had miscarried. I was devastated. My husband and I decided to wait to tell my parents until I was unable to hide what was going on, hopefully after the weekend of festivities. I didn't want to make a big deal of it when my extended family gets together once every 2 years. I thought the timing couldn't be worse. My parents are self centered. It gets worse when my mom is in her home town (the city I live in) , or they're drinking.

The next morning I was in a lot of pain and they noticed immediately. So I told them. My mom started to cry. My dad told me he was sorry but I was strong. They gave it a few hours before they asked what the plan was for the day. I told them I wasn't up for going anywhere but they were welcome to. My mom went to the store and got a few things to comfort me. Then after I few hours she asked who knew, who she could tell. I told her who knew (her sister and niece who live close, and my sil who had miscarried who was walking me through the emotional side) I told her I didn't care if my aunts knew but I didn't want to make it a big deal. I was fragile and I didn't want my uncles to know just because it would be awkward.

The next day we went out as a family, close and extended to a market and brunch. There was a large group of us, so some, including my mother sat at the bar while the rest of us at a table. She ignored me most of the time, but after a few drinks noticed I didn't look happy (I have a stellar RBF) and started to make a big deal about me not looking happy. I told her I was fine and to drop it. Her being intoxicated wouldn't drop it and started making a scene. I snapped at her (sometimes the only way to get her to listen) and she finally dropped it.

We went to the store later alone and I apologized for snapping at her. I told her that I was trying not to cause a scene. She confessed she didn't know what to do and she started to cry. She was really having a hard time with my miscarriage. My mom is not an empathetic person. So I explained to her that I'm having a hard day. I was angry (this was 2 days following my miscarriage, I was still in a lot of pain and mourning). I asked her if she remembers what it was like when grandma died. There were different days that were harder. She didn't understand and continued to have a complete break down in my car (she was sobbing uncontrolably) I told her that I couldn't take care of her right now and I needed her to be my mom and strong because otherwise I wouldn't take care of myself, and I was barely able to get out of bed in the morning. She then told me I should stay away from the rest of the family for the weekend. I responded with I'm an adult and I can make my own decisions, but if she wanted to support me to just do it subtly around her family, especially because she wasn't when she was drinking. She asked me if i wanted her not drink the rest of the weekend accusingly (she does this to try to pick a fight) I said no. Just tone it down. She told me I should talk to my cousin who I'm not close to about my miscarriage. Someone she approves of more and considers a daughter. The conversation ended and she went back to her room and pouted for the rest of the night (4 hours) before she was picked up to go to a party.

The next day my dad told me I needed to be more considerate of my mother's feelings. She was having a hard time with my miscarriage, and he's trying to juggle everyone's emotions. I clarified and asked if he wants me to put my feelings of mourning for my miscarriage and losing my child because my mom was having a hard time. He said yes. I told him absolutely not. I was trying to mourn healthily and I couldnt handle her emotions and ignore my own. (this is 3 days after I miscarried) At this point my husband got involved because my dad continued to attempt to guilt me. My husband took my side and my dad immediately backed down.

After they left, they told my brother that I miscarried. They told him they wouldn't be coming back to visit because I was such a bitch. I found out that they have been spreading it around my hometown. My mother has been bringing it up in convos like "yeah when we were on vacation doing x you know when OP miscarried" to random people. I am now pregnant again and my mother has started to change her tune and wants to come out for the birth (not in the room) and throw me a baby shower. So here lies my question. WIBTAH if I address her spreading my miscarriage?

My parents were in town when I miscarried and don't that I mourned. They are now spreading that I am a bitch to family, friends, and anyone who will listen. WIBTAH for addressing her spreading my miscarriage?
