Am I over reacting

So my whole in law side of the family knows that we’ve have problems with pregnancy in the past & just because my MIL got mad at me (she’s back on pills again but I can’t be the one to point out the elephant in the room) she told everyone we are pregnant. She suspects but we haven’t even told her because it’s wayyyyy to early. I’ve literally had his sisters texting me all day asking if I’m pregnant.

I just feel like she stole that initial surprise of telling everyone from us. we’ve been married 5 years...
