Emotional mess

So, hubs and I currently have 3 girls. Mine, his, and ours. I've had 2 c-sections due to my first born being breach and unable to turn. Then, after our youngest was born, I miscarried twins at 12 weeks. I am currently pregnant with our rainbow baby. Well, yesterday I took our oldest to the pediatrician and the nurse and I started discussing my pregnancy, and she mentioned how since it will be my 3rd c-section it will be my last baby because they tie tubes on the 3rd c-section because it becomes to dangerous. Well, I've never heard that before but it really makes me so sad. I seriously wanted 1 or 2 more babies after this! 😭 Does anyone know if that nurse is correct on what she said? Man, I really hope not!
