Am I over reacting ?

I’m 7 weeks pregnant and decided to tell my mom only because I needed someone to talk other than my husband. I told her not to tell anyone because we’ve had miscarriages and an ectopic pregnancy in the past and I’m not ready to tell anyone else other than my mom in case I lose this one too. Come to find out today from my grandma she told the entire family and I have everyone calling and texting me to find out what’s going on with this pregnancy. I asked my mom why she did that and why she thought it was her news to share and she said “ because I can “ she’s never done this before idk why she did that but I’m very upset because that was my news to share if this baby sticks and I feel like that was taken away from me I wasn’t ready to announce it.
