I have always wanted kids. A planned surprise that I would learn about at home when my period ended up being late. That just hasn't happened. It is not fair that we need help conceiving. How do you know when it's the right time to try help? We have tested and have unexplained infertility. We have been trying 2.5 years and doing everything within our power to conceive on our own. How will we know it's the right time to get medical intervention?
