OB appt in morning... Tips?

This is our 4th cycle ttc, I was thinking it was #5..& they could go ahead & do a SA on dh..? But now I’m worried they won’t since it’s only the 4 mos. However, he ttc for 10 years w his ex wife. Hopefully they’ll take that into consideration..?

Any other advice on questions I should ask or tests I should request?

I’m having my prolactin checked again bc it was very high when I was breastfeeding & one suddenly started getting milk again. (Dried up completely in Jan)

I’m 36 & have 3 kids ages 1, 12, 15. If that matters. I know our issue could still be me.
