I am trying to conceive baby #3. With the first 2, we conceived on the day I ovulated in the 1st month of trying, and now have 2 wonderfu boys!

We would love to have a girl, and I have been reading about the Shettles method. My 18 mth old DS just self weaned a few weeks ago, so I am just guessing on what my cycles would be like now. I had 3 periods while he was nursing in the past few monthes, which were 45 days apart. I am assumed that my cycles would go back to what they were before, which was 31 to 32 days apart. Judging by that I should have ovulated yesterday(5/8) or today(5/9). I have been taking ovulation tests, and they have gotten darker, and looks like an almost positive today, and yesterday I had very noticeable ovulation discharge. We DTD on 5/5, 5/6, and 5/7.
Anyone else use charting with the Shettles method? Anyone have any examples of getting pregnant after having intercourse in the days leading up to ovulation, but not on the day before or day of ovulation? Thanks!!
