Infertility

Tried for 4 yrs for our first baby and it was a long road full of many negative test to find out it was male infertility he started on a supplement to boost his count and 3 months later we were pregnant now we have a beautiful 2yr old and we are ready to give him a sibling but they stopped producing the supplements he took (sperm xl) and so far different ones havent made a difference. With all that to say we always talk about how hard infertility is and how it brutally hurts not being able to have a child but we never talk about how sad and heart breaking it is to not know if you'll ever be able to give your wonderful miracle baby a sibling
