Hi all I wonder if anyone can help interpret my bbt chart. There hasn't been a significant shift at all. I did have what I thought was ovulation pains and that corresponded to the slight rise on day 16. This is my first cycle bbt and I did it because I thought it was odd that with a 28 day cycle I was getting opk peak on day 19. This is cycle 4 and this cycle my clear blue has not had a static smiley. If anyone can give insight into my chart or even some hope that would be so helpful.
