Today is period day and this morning my temp gone up a bit which is 36.66 yesterday it was 36.59. Please advise if I have any chance I don’t want to do the test now and be heartbroken so I will wait for 2-3 days more. This is my today’s chart. Please advise.

If you had sex around the time you ovulated then yes you have a chance. A test would be accurate by now since you're 14 dpo
