I have 2 kids and have been infertile sine last baby 13 yrs ago?

See a REI specialist: 13 years is a long time ttc. See a fertility specialist (reproductive endocrinology and infertility or rei) to get checked out - they will check for low egg supply (diminished ovarian reserve), hormonal problems, not ovulating, blocked tubes, problems with your uterus, or sperm problems. Even if you had a baby with the same partner there may be sperm issues. Surgery is rarely needed ...

Need Full Evaluation: That suggests that there is something significant going on. Even at a young age, you deserve to have a full evaluation by a fertility specialists. Most likely surgery is not going to be the answer. 13 years of infertility likely suggests the problem lies with the tubes or the eggs and there is a high probability of needing advanced fertility treatment.
