Annoyed and pregnant

So since finding out we have an induction onFriday, boyfriends mom has been telling us about all the horror stories of the babies in their family and how one almost died also sending us a "cute" video with childhood cancer contributed to it. Now after freaking out and worrying about the baby he tells me to fucking chill and I said well why would she say all of this to us when were having a baby Friday and then he starts screaming at me for freaking out! His mom has always been an issue and I'm at a loss.
