I definitely know your struggle. It's difficult, having a toddler and being pregnant. My kids are 4, 3, 2, and 9 months old. I've been through many pregnancies in your predicament - tons to do, nobody to help... Feels like you're going through it alone, but you're not! So, maybe I can offer some tips if you ever need them. DO feel free to message me. The most important part is having your child on a concrete schedule so that you can make sure you get everything done that you wanna do and you can also rest and maybe even nap. My kids' bedtime is 7pm. They read in their beds until about 7:30 pm, and they're not allowed to leave their rooms - except to use the bathroom - until 7:30 am (OK to Wake clock). This means that I've got 2-3 hours at night to do what I need to do and still get plenty of sleep. My 2- and 3-year-olds nap from 1-3 pm. I spend one hour of that time cleaning and one hour homeschooling my 4-year-old. If you need more time, freezer cooking or once-a-month meals might be great for you. I LOVE keeping my freezer stocked with meals that I can just pop into the oven with no prep work besides thawing out the night before.
Also, toy rotation encourages the kid(s) to play with their toys longer and to enjoy them more. I have several bins of toys and pull out only one at a time. Of course, you have to have the room to store all of those toys.... I have a huuuge cabinet full. Desperate times, right???
