It is not really known for how long after ovulation you are fertile - some people think for up to a week. Did you only DTD on the 29th or on other days? If you did DTD before the 29th, it is possible for sperm to look like fertile CM. Fertile CM is usually completely clear, like egg whites (crack open an egg and have a look if you're not sure and stretch it between your fingers). If the globe that stretched all stuck together, it may have only been sperm and you may have already ovulated. Judging just on your observations, I would be guessing ovulation on CD14 - the 26th. I could be wrong though.

The only way to know for absolute certain that you ovulated is to temp. It is possible to get all the other signs of ovulation but unless your temp rises ovulation can't be confirmed. The other observations are only secondary and temping is the most accurate and reliable.

Sorry my answer is not entirely clear. I am not exactly sure what you were asking ...
