The reason why it's suggested to make love regularly, two to three times per week, is not just to take the stress out of TTC (though in and of itself that doesn't sound like a bad idea). Making love two to three times per week, every week, will probably get you pregnant faster as you won't miss the day of ovulation. Egg-white cervical mucus first appears a couple of days before ovulation. But you can ovulate even without EWCM. To try and "time" sex by EWCM and making love just when you are about to ovulate based on EWCM has never been conclusively shown to improve your chances of getting pregnant, because ovulation does not always happen exactly when you expect it. And making love after ovulation won't get you pregnant.
