sperm analysis

I have really bad anxiety and now I'm really over thinking, my SO has got to have a sperm analysis done and the doctor said because he already has a child, if any of the fertility treatments don't work (<a href="https://glowing.com/glow-fertility-program">iui</a> etc.) we can't have <a href="https://glowing.com/glow-fertility-program">IVF</a> im so upset and scared that if nothing else works and we can't try <a href="https://glowing.com/glow-fertility-program">IVF</a> I'll either lose the man I love so I can have a family or never have a family to be with my SO I can't stop thinking 😢
