I honestly don't know where to begin. This is my 1st cycle charting so forgive me for not knowing much. My chart has no coverline or crosshairs so I'm guessing I'm not ovulating however I've had 5 days of extremely positive opks. (CD15-19) I ran out of opks on cd19 and didn't get anymore but I'm guessing if I had opks they still would have been positive. My temps seem to be all over the place. I believe a few of my lower temps recently are due to the cold weather we have had and my room always freezing. I have woke up without covers and with my mouth opened before but I put my temps down anyway. Please if someone could give me some insight I'd be thankful!
