Hi i have been ttc for the last 9 months, cycle is usually 29/30 days so i thought i normally o/v around day 15/16. Decided to use an o/v test on day 18 and got two lines!! Does this mean that my cycle will be longer? Don't want to test too early but not sure when to test, really positive this month so don't want to disappoint myself before I have too! please help
