Can someone explain to me how to read these? I do have 2 days I missed temping. I had pos opks on the 8th morning to 10th morning. By noon is was back negative. I took a pregnancy test couple of days ago and may have seen a vvvfl but then again could have been an EVAP. Haven't tried since. Waiting to see if I start which is due on the 24th. Charting is confusing to me. This is my first month btw. I take temps at around 7 in the am, orally. Thanks in advance.
