Hello! First month trying and fresh off of birth control. I started checking my BBT this week as well as OPKs at night. I know the brand I got says second morning urine is the best, but I see patients in clinic all day so it’s not the easy. They’ve been negative. However, my BBT is up about half a degree F from the day prior. Could I have just missed my LH surge? I know I need three days of elevated temps to suggest ovulation, but just looking for others thoughts.
