chart analysis help

Shannon
Here's my chart...  does it look promising so far?  I'm so scared because my DH had a vasectomy then a reversal. He had a child with his ex after that but we're old now (he's 43 and I'm 42) so mI'm not sure if has good swimmers lol  When should I test?  I'm thinking first Saturday then again maybe Tuesday?  Any feedback would be awesome, thanks!!
