I need advice

Okay so I’m Air Force active duty and you know when your pregnant they put you on the profile and you can only work a maximum of 8 hrs a day...

So I currently work 9hrs no big deal I’m not complaining you know but we’ve recently gotten a new supervisor and she really doesn’t care about anything but herself and I tried to ignore it but now I’m exhausted all the time because I’m working half the time alone cleaning bending pulling she even recommended me for a TDY in June when I’m due July 16 😑 and now she’s trying to have me go to another facility to shadow someone and learn there job like this is overwhelming and stressing me out Any advice I was told but some Coworkers talk to my doctor about getting my work days cut in half I just need some advice cause I’m only 25 weeks
