How do moms have other babies after first pregnancy being horrible

I’m at 29 weeks. Had a bad night. Woke up at 4 by a nosebleed, all night feeling sciatica pain on one side and the other rib pain. At 7am super nauseas, decided to eat cuz wasn’t going away and figured i was hungry. Half way i had to run to the bathroom. Didn’t make it to the bowl. Puked everywhere. My husband is the best and cleaned everywhere cuz i just had no energy left after that throw up. How am I supposed to think about baby #2? I stopped work 2 weeks ago. Am I supposed to stop working each time. Like it’s not right. We both come from a large family. I at least wanted 2.
