Dr sending me to l and d and Rant husband omg

So my cervix was funneling and starting to thin two weeks ago (3.3 and ob wants it to be 4 or more). I was told to stop exercising except walking. A little Back sorry my hubby is a power lifter and needs two hours a day 4-5 days a week at the gym. We have an agreement that we go together or don't go. So even after the dr has told me not to exercise hubby has pushed and whines about going still. So I have and done some waaayyyy lighter exercises than is my norm (example i deadlift not pregnant 240 lb and more some days and cut it down to 100 most days and did this with every exercise).
