Thanks for your replies. It definitely feels good to share! especially with people who've been through the same sort of thing. I tried doing the OPK thing for the first time last cycle. Tested for 9 days. Got a faint line in varying shades every day. On day 18 the line was darker but still not as dark as the control. I will keep doing the OPK and start charting temps aswell. I am going to go to the GP anyway and just have a chat. I don't think there will be any stretching of the truth though! Believe it or not, that was also my Mum's suggestion! Anyway, thanks so much for your input. It helps a lot.
