Appropriate working hours šŸ˜”

I don't want so sound like a typical preggo but this sh* hurts! Being in the military and having to work 12hr watches For 5 days this week is pure torture..Ā 
Being in my second trimester (15weeks) & nothing that "was suppose to get easier" is ! I just don't think this is acceptable. I don't know if medical will help me out granting me a 10hr work day up until my 28th week when we can only have a 40hr work week. BUT..
I might just have to bite the bullet with this one. But, it's tough. I just think it would be better if I could have normal working hours (like a 7:30-4 maybe?!) but that's just me šŸ˜©
