Steroids

I caught my husband using steroids about 6 years ago and I flipped out at him and told him I wasn’t ok with it and threatened to leave if he didn’t stop. I also told him if I ever caught him doing it again I’d divorce him. Fast forward to now and 2 kids later and I’m 7 months pregnant with our 3rd. I caught him looking up how to get rid of water weight caused by test E (steroids). We just had a huge flow out argument and he swears he’s not on them but he also said he wanted to be because he wants to do body building and see how far he can go. He is already is super shape and goes to the gym every day. He doesn’t need steroids (that is if he isn’t already on them). What would you ladies do.... he says I am blowing this all out of proportion but I feel like he knew what he was risking and did it anyway. What would you do?
