Ric-I brought a clear blue fertility monitor from the UK it was $150 you also buy a pack of 20 test sticks to use in it the way it works is on day 1 of your cycle you set the machine then every day around the same time you turn it on until on about day 6 it asks you to do a test same as an opk then you put it in the machine and it reads the two hormones E2 and LH i posted a pic of the lines to show how the LH gets darker and the E2 gets lighter as you approach ovulation and the machine will give you a reading of low high or peak so you know the best time to BD to conceive so far it has been great no guess work as the OPK's can give you a false reading if you miss the window of LH surge or like me the OPK's were positive for 10 days so i wasnt sure if i BD at the right time.
Under my signature is a link to photo bucket i loaded Abbi's montage there it is not as good as the slide show or as clear but pretty close if you have office 2007 i can email it to you which is much nicer to watch we tried everything else to change the slide show format but nothing worked.
