Was going to post this in the other thread about taking temperatures but thought I would post it into 'swapping tactics' instead as I thought it was appropriate. This isn't recommended by the fertility books and Toni Weschler (sp?) would kill me for saying it. But what worked for me was to take my temperature at the same time each day but early evening. I actually took it at 5pm each day as I walked in through the door. This was particularly helpful in the winter when it is really hard to wake up and take temperatures in the dark. Even though the books don't endorse it, I did get a definite thermal shift every month doing it this way. In my mind, charting your body fluids, temps, etc is the only way to feel totally in control and know exactly what goes on in the body. All the other methods just seem to let someone else make the decision for you. Providing you haben't just come off the pill, you should notice a rough idea of when you ovulate from as soon as the second month. But in the mean time while you are waiting to see a pattern, try the 'leave it for eight days and BD every other day' method, so that you are doing two things as once. This is what worked for me.
