Venting Expecting and Crazy in law!

My DH and I found out early that we are expecting the Due Date is Thanksgiving! 
I currently suffer from HG and was taken to the hospital and given the news of Your Dehydrated and Pregant 🤒🤒🤒! 
On our way home my DH decided to stop and tell my DH dad the news (DH mother is deceased 18 years) only to find out my step-Mother in Law was home 😞😞😞 DH still shared the news and she was pissed off on top of our unplanned visit.
She had the nerve to ask us why we decided to have sex that week and have a baby due on Thanksgiving and this year of all years because my husbands step-brother (who I've never meet married for 6 1/2 years) family's turn to hoste Thanksgiving Dinner! 
My Father in Law was happy and even said that it's plenty of time to ask SBIL family if they can hoste instead due to wanting to be in town for the birth. Well today I get a email stating the Rules of Delivery and what she will put up with.
Since she is hosting Thanksgiving Dinner and IF I deliver on my due date my DH can only call on my FIL cell phone 1 time and leave a message we are not to call on the house line! Dinner is from 3 to 6pm we are not to call during dinner! 
She then proceed with her normal rant and rave about how put out she is by this and so on! I could honestly write a book on her more like a survivor guide to dealing with crazy in laws!
