Getting Pregnant

So, my boyfriend really wants a baby, and I completely understand that, I’d love to give him a child, I also am very scared... Once I was told that I can’t have anymore kids due to my previous c sections, but also get told the doctors where I live are not exactly doctors. They are here until their internship is acheieved then they leave. Have giving half the town false information, have blown a vein in my hand and caused such issues with me. Also got told I can have one more before it causes medical issues... but like I’m scared to give a child to another man, and he change and we separate again. My kids now have the same dad and we haven’t been together in 2 years. Just very very scared...
