So I just wanted to write this post in case anyone else had went through this and needed some hope. So here is my story. I normally always O on cd 13. This cycle my OB wanted to try me on Clomid as a last resort before referring me to an RE. On cd 12 I got a positive opk. On cd 13 I got oculation pains so I was sure I ovulated. I continued to chart my BBT but I wasn't getting any rise. Actually my temps were dropping. I thought I must not have O'd and I was so upset. Well on cd 18 I got blood drawn and low and behold my doctor said I most definitely ovulated around cd 13. I didn't get a significant rise until cd 19. So I am proof that not everyone gets a temp rise right after O.
