Saw my OB finally at my Aug 31 appt to find out my results.
And everything was normal. Me, DH, everything - was normal.
So my guess is probably my age? maybe lifestyle-related (diet, exercise, sleep, etc)?
Next step now is to get a consultation with the fertility clinic. I've been told that they may recommend IUI if I don't want to go IVF (and I'm honestly not sure I really want to at this stage). I'm gonna call them tomorrow and get that appointment set up right away.
After all - I'm getting older all the time.
