Butterfly- have you been to your doctor to see if they can refer you? Also are you taking temps at the same time each day. If you click onto my chart and scroll down you'll see for the first few attempts at charting I've been all over the place with them. I started setting the alarm to go off before OH gets up for work and taking temp then going back to sleep without looking at it. My thermometer stores it so i check it when I get up. I have also been checking CP, this is what caused me to do an OPK when I got the positive as it was more open than i had ever felt it.
Fx'd and baby dust to you both
