Sister spilled beans about my miscarriage when I wasn’t ready

My husband and I found out we were expecting our 2nd child, we had been so desperately trying for for almost 2 years. We got really excited at the 9 week mark and shared the news to EVERYONE.. as you can imagine, when I started bleeding and eventually full fledge miscarrying I was devastated beyond belief.. it took me weeks to finally get out of bed after medicated treatment etc. I’ve never been so sad about anything in my life. When I began to recover from the grief my next feeling was embarrassment that I had told people.. I just could not, and still haven’t been able to come to terms with telling other family members we lost the baby.... I did tell my mom and sister when I saw them at Christmas Because I felt I HAD to... well I found out recently my sister, who has always been really unkind to me, felt it was okay to tell my dad and step mother, and brother ..something about that doesn’t sit quite right with me...we have immediately started working with a fertility doctor to try and get pregnant right away. I was secretly Hoping I’d get pregnant the next cycle and it would help with the fact that I might not have to have that difficult conversation, at least just yet anyway.. am I in the wrong for being a little upset that my sister decided to tell people about the miscarriage ?
I’m sure it came up when they were like “how’s she feeling“, “isn’t that great she’s pregnant again” and she responded with oh she lost the baby.. but if it were me, I would’ve been respectful and said she’s great! Yeah you should check in with her last I talked to her she was doing well...I’m at a point where I feel like I can’t forgive her. I’m so mad.
