We are TTC baby no. 2. This is my first month of using OPK and tracking BBT. I’ve had 1 low day and 9 high days with no peak. The instructions state that this happens to 1% of people. Has this happened to anyone else? I haven’t had a sharp rise in body temperature either so perhaps maybe I just did not ovulate this month? I have a VERY regular cycle of 28 days and I’m on CD 16 now. Advice?
