Awkward convo with gym coach

So about three weeks ago I found out I was pregnant. During my last pregnancy I had diastasis recti (when your abs separate vertically). I felt like I made a lot of progress healing and didn’t wanna lost my progress.

Well I workout at a local gym which only offers fitness classes. I only attend the evening classes and have the same fitness coach every day so we are good acquaintances. Well just last week I told him I needed to modify some of the core exercises due to being pregnant again and having the diastasis recti.

Well... today I am miscarrying. It’s painful both physically and emotionally. I also will be taking the next two weeks off from the gym to heal.

Do I message my coach? Do I tell him? It’s so awkward and it’s totally my fault for telling him so early in the pregnancy. I let my excitement get the best of me and I know I will have to tell him eventually as he is finding modifications for some of the class workouts for me. Ugh how do I go about this?
