If ovulation strip shows smiley face, what does it means? Does it means I am ovulating and can conceive if have intercourse today? How accurate is the OPK?

If your mense is regular, you can use the 7-test kits. The ovulation test will tell you the best 2 days to conceive (LH surges). You need to follow the instructions on when to start testing, so that once you get the smiley face on the test, you should intercourse within the next 48days. The smiley face indicates the best chance to get pregnant, as the egg is waiting for the sperm before it ruptures. You can enter your last mense date and duration of your mense cycle into her and it will tell you when to start to test daily after mense http://www.clearblueeasy.com/start-testing-with-clearblue-easy-ovulation-tests

Nobody can guarantee conception. You have to find out when your most fertile window is. Conception is likely to happen when your egg is fertilised 5 days leading up to the day of ovulation. The easiest and most fuss-free way is to have sex every two or three days. http://www.babycentre.co.uk/a1809/when-is-the-best-time-to-get-pregnant
