Seeing an RE and the plan

Melissa A • DS 4/6/06. DD rainbow 10/19/15. Pregnant w/ #3 due 10/3/18
Has anyone seem an RE yet? If so, what were your recommendations from him/her? 
​We just saw ours for the first time. Since I ovulate normally and dh's SA is (supposedly) ok, he recommended some lifestyle changes while we keep trying naturally and run more testing beyond what my obgyn did. 
​He's testing: 
​1. My prolactin
​2. My cervical fluid for infection
​3. DH's semen for infection
​He recommended the following lifestyle changes for DH and me:
​1. No hot baths for me (it can affect egg quality).
​2. Wear gloves while I work (I work with glass beads often coated in colors that can have heavy metals)
​3. No more than 2 cups (16 oz) coffee per day for DH
​4. No more than 2 drinks per day for DH
​5. No more than 1/2 pack cigarettes per day for DH (he's trying to quit anyway)
