Birth control paranoia

So, I'm about 14 weeks with my second child. I'm a single mom and I have no intention of having another baby after this one. At least anytime soon. Birth control always makes me really sick and uncomfortable or causes extreme weight gain. Especially the "long-term" options. I know condoms are always an option and celibacy. Again, single so I'm not planning on popping this girl out and then finding another stick to ride, I just want to be prepared. Which options have worked best for you? I have only used depo which I am terrified to use again, and then I think the mini pill? But it made me feel so weird and lethargic. Just looking for some advice. I might want another within 2-3 years but I'm unsure.
