May your dream come true, my love! I can feel you that how badly you want a baby. You are a brave lady as you are bearing this pain for the last 7 years. It's such a long duration for anyone. Can you please tell me why you've not tried some artificial treatment? This can be ignored as you are now trying your best to overcome this issue. Well, in older times, adoption was the only option left for infertile individuals. But with the passage of time, science has made progress in almost every field of life. Infertility treatments such as surrogacy and IVF are introduced too. So, I personally suggest you to go for surrogacy technique. In adoption, the child doesn't belong to you in any sense. While in surrogacy, the child belongs to the IPs biologically. You'll be satisfied with it too. A clinic is even providing a guarantee for her surrogate and success experience too. May you get your desire soon!
