I am diagnosed with a Fibroid of size 13*9mm in the posterior myometrium in Ultrasound. Is there any cure for it??? Can I conceive a baby? Please help

Yes you can. Most uterine fibroids are benign muscle growths which can be anterior, posterior, lateral, inside the wall of your uterus, on its inner or its outer surface, ...and of varying sizes... If yours, which is fairly small, is not on the inside uterine lining, if it remains unchanged and you are healthy +asymptomatic your chances of getting pregnant and carrying your pregnancy to term are excellent.
