Hi Chuck,
Not sure if this will make you feel better, but on average it takes six months to conceive, although you are slightly over this, I would still try and relax and enjoy the practising and once it gets to a year perhaps keep diaries and speak to your doc etc. The time period for conception is so small so it can take time.
It took me 4 years to get my pg, I hope you get it before then. Relaxing is the key but I know it's hard as you can't help thinking about it.
Also think about what you and your partner want, not what the family want, it's your situation not theirs and they will only stress you out.
Good luck !!
