Here are some tips from the users of SteadyHealth, who have been there and done that. You will have to figure out what works best for you and your partner, so some of these tips are mutually exclusive.
Have sex when you feel like it
It is no secret that you are more likely to get pregnant if you time your intercourse during the female ovulation. Nonetheless, couples who have regular unprotected sex, only when they feel like it, are not at all unlikely to get pregnant. If you and your partner have an aversion to the idea of doing the deed when the clock tells you to, forget about ovulation calendars and tests. Simply be intimate when you are both in the mood.
Pamper yourselves when ovulation comes round
See what I mean about being contradictory? Some couples thrive on making their "baby-making sex" a special event. Book yourselves a nice hotel for the night when your ovulation test turns up positive, enjoy each other and give your partner your full attention. You can create a special atmosphere at home as well get out the scented candles, massage oil, and perhaps even sex toys. Engage in lots of foreplay and have fun. Quickies tend to cause stress.
Talk about it
If you feel sex has become all about making a baby, and you are not enjoying each other any more, tell your partner and discuss making things better. Having a baby together is a big adventure and it should be pleasurable, not a chore.
