How is the temperature spike post ovulation defined? Is .4 degrees enough to show ovulation? I am currently on day 15 of a 27 day cycle. Yesterday and day before my temps were 96.76 and 97.18 and today it was 97.60 OPK was positive yesterday. What do you think? Think I ovulated on Day 14? TTC for on cycle #5. I am hopeful but not putting all the eggs in this basket (no pun intended) as I was super stressed out this month. Also, is it normal to have ovulation pain for 3-4 days? THX!
