Not prepared

I had my tubes tied in 2016. Well I've not had a period since August 2020. I didnt think anything of it at first due to my tubes being tied. Well in October I took a pregnancy test just to ease my mind and it was negative. So I called my Dr and told her what was going on, she said since my tubes were tied and my test was negative then it's probably just hormones. I'm only 29 so I didn't think about menopause. Well I got sick last week and went to the ER and found out that I am 32 weeks pregnant. I've bad mo symptoms, I've gained some weight but just put that off as quarantine weight from staying home and working from home. I don't "look" pregnant just chunky lol. Im not sure how I didn't feel baby move or get any symptoms. My dr says is because my uterus is turned backwards. But idk. I've had 4 babies. I feel like I should have felt something. Now I feel HORRIBLE I've had no prenatal care. I've took no pregnancy precautions. Which I don't drink or smoke etc. But I've been working on my farm, I even went to an amusement park last month and rode coasters. I just want to cry. I am not prepared for this.
