Ivf treatment blocked tubes

My name is Taja, I am currently struggling with infertility due to one tube being removed and the other being blocked. I had my son when I was 15 yrs old and never been able to get pregnant again. My son father and I are still together my son is now17yrs old and I am soon turning 34. Never felt there was a good time to get pregnant again but now as my only son just graduated high school I feeling a strong urge to mother again this time at an adult age. Please please help me to grow my family..
