Should I keep working?

Hey Momma’s and everyone out there! I just had my first OB appointment earlier this week and found out that I am a little further along than I thought😅😅. I’m 15 weeks and the problem is my job. I work full time 40+ hrs a week and I’m exhausted. Beyond just that. I struggle everyday at work. Morning sickness, headaches, it’s been harder to concentrate and really amp myself up to keep going . 15 weeks doesn’t sound like a lot, and this is my first pregnancy, but I didn’t expect for all the symptoms to really hit me this bad. I work at a hotel at the front desk, so imagine trying to hold back morning sickness in the midst of everything. The constant motion of just seeing everyone walk past and the smells that come out of the breakfast area, it’s all overwhelming sometimes. I was able to do my job pretty well before the pregnancy, but it’s really affecting my performance now. And to make things worse, my boss is really strict. She doesn’t see my pregnancy as an excuse for anything to not get done or not be seen all the way through. No excuses and no leaving work for someone else. Not that I try to, but staying on my feet for long hours dealing with the public, and paperwork, and even baking cookies for incoming guests, I’m ready to explode by the time my shift ends and having to do it five days a week is hard. I need advice on what to do, why to say, and when did you Momma’s all quit work? I’m trying to hang in there long enough to pay for my gender reveal party, but even the thought of work makes my stomach upset. Please help.
