Anyone else got a high pressure job?

My job is extremely intense around the beginning of the month, I work as a business Analyst so basically communicate the profit or loss & all the details to head office on the company. Last month end I would start at 7am and one night I didn’t get home till 11pm. I didn’t know I was pregnant then but now I am & I feel so tired & unwell in certain periods of the day I’m not looking forward to pressure again. Also suppose to be going to Brussels next month 😔. I don’t feel like I can tell anyone as I’ve had 2 miscarriages but they were before I started my new role in May. Any tips? Xx
