Someone please help idk what to do😞

So I’m 15 weeks and I’m constantly dizzy and lightheaded and im always in so much pain from the beginning of my pregnancy in my back and stomach and hips and it still hasn’t gone away, (yes ik pregnancy isn’t comfortable but this is just way to much to handle) i just started a new job today and I’m constantly on my feet and i feel 1000x worse then i usually do, my anxiety doesn’t help any situation but now my stomach is starting to hurt so idk what to do. My boyfriend wants me to continue working because we obviously need money for the baby but idk if my body can handle it! He says every other women in the world gets pregnant and is fine im just nervous he thinks I’m making it up so i don’t have to work! We plan on going to the hospital tonight when he’s out of work to check what’s going on and I’m hoping they tell me to lay low! Idk what i should tell my drs and my boyfriend if i end up not being able to work all the time. I just don’t wanna be a bad mom😞
