Your temperature may go up and stay up above the coverline for 14-16 days after ovulation. That is called a "biphasic curve".
When you get your period, your temperature will usually go down within a couple of days before or after the period strarts. Temperatures can sometimes stay up above the coverline for several days even after you get your regular period. That does not necessarily mean that you are pregnant, and if you are bleeding like a regular period then chances are that you are not pregnant.
However, if your bleeding was much less than a regular period and your temperatures contain to stay up then you may want to take a pregnancy test.
