I am a Newbie at BBT! please answer.

so.. I started the 1st day of my cycle charting my temp, my fertile week I went on vacation and I forgot about it, so for 4 days i didn't get to temp.. I started back temping this morning. my question is after ovulation does your temp stay high until next menstrual cycle or what usually happens? my temp has been 97.35-97.70 for about a week and a half, my fertile week I didn't temp, and today it was 97.95? so it's went up pretty high compared to what is was? so do you think ovulation actually happened?
