So I was planning to announce my pregnancy tomorrow 🙃 but I don't know now

So my sister in law came over to my house asking for help with something she started telling me about how she wants another baby but a girl since she has all boys and this bitch brought up my miscarriage she flat out told me you caused it because you didn't eat enough and all you wanted to do was lay down ,my blood insanity started to boil and I can feel my vein in my head pumping I wanted to choke this woman and bury her in my backyard I had to compose myself i simply said I did not cause my miscarriage how dare you imply that how would you have liked it if I said you caused your miscarriage by cheating on your husband 🤔 but I would never say such thing and I told her you can get the fuck out ! I instantly bawled my eyes out how can someone say something so horrible. Now I don't even want to announce anything at all my husband said I should that i shouldn't let her take something so beautiful away should I just do it and obviously not involve her ?
