Well you need to test for ovulation usually around cd 11 which you count your cycle days "cd" your start of your period is day 1 so around the 11th day start testing, try not to have sex till you get your ovulation stick positive, so the sperm is more stronger, and can reach the egg. Usually ovulation is 14 days but I would get my lh surge around cd 12 so you would then have sex and try. Best of luck to you
your fertile days will be the 17-22 good luck (:
