What happens after

So I’m currently trying to conceive my second baby. I’m super happy and excited and would love for my son to have a sibling close in age and all that fun stuff. as much I want to be pregnant so very badly, I start thinking about my last pregnancy and how hard it was on me. I was miserable most of the times. Wasn’t in a good living situation, my boyfriend wasn’t in his right mind. I was sick ALL the time. Had to take three different nausea meds during to keep just water down. I was in so much pain. I’m in a wayyyyyyyyyyy better place then I was back then, but now I’m scared about this. pregnancy’s are different right? Like I have a chance of maybe not being miserable if I get pregnant again? Im terribly scared...like terribly. I’m such a wimp when it comes to pain and sickness. I want good health with this next pregnancy. Anyone feel this way? It’s a scary feeling :( birth wasn’t to big of an issue I actually loved the adrenaline of it all it was great. But the whole 9 months of throwing up and anxiety SUCKED. anyways yeah I’m scared shitless
