The general rule I’ve heard is that if you are under 35 and have been actively trying for a year with no success, it’s worth progressing to a fertility specialist. Over 35 - give it 6 months.
We tried for a year, and during that period we had some basic tests, and found that I had polycystic ovaries (but not PCOS), but no other explanation. We temped, checked cervical mucus etc, used non-sperm killing lube, OPK, multivitamins, the lot.
When we finally went to the specialist, we found that the basic sperm test Boy from Mars had had was inaccurately done (a risk in non-specialist labs), and based on his sperm count we have a 5% chance of achieving this naturally.
We’re just starting our first cycle of ICSI this month, which seems to offer 50% success rates.
Which means there is a 50% chance of it not working. That’s important as it’s significant enough that we may never actually have kids. Now, I hope that we do, but we’re both going into this with realistic expectations, and are continuing to focus on lots of other things, so that ‘we must have kids or everything else will be shit’ will not become our mantra.
So my advice is get yourself to a specialist and check everything again from the beginning. I took a year’s worth of charts to him to show clear temp shifts and correctly timed intercourse, which helped convince him immediately that something odd was going on - I think this very much helped.
And talk to each other about the process - how much either of you want kids, what you’ll do if that doesn’t happen etc. I hope that this turns out to be solved quickly and happily for you, but it can be a rocky road emotionally, and it helps to know why you’re going through all of this, and that there is a light at the end of which either tunnel you end up going down.
