It might also help to start temping. A friend of mine has a very irregular cycle - she was never easily able to pinpoint ovulation (cycles ranged from 35 days to three or four months). The approach they took was to have sex every other day from the end of her period. That way they were pretty much guaranteed to hit a couple of fertile days! That's an awful lot of sex - but it did the trick for them.
