Re: preg. test
Usually you will take the pregnancy test about 2 weeks after ovulation which occurs about the 14th day from the start of your period (if you have a 28 day cycle). To figure out about when you ovulate, figure out the length of your cycle. If it's 40 days (longer than average) then you will probably ovulate about day 26 of that cycle (2 weeks prior to your next period). Anyway, I think this might be a little confusing, but just remember, most tests are accurate when taken the first day of your missed period, so it's best to wait until then. Good luck to you.
