So I know when you ovulate an egg only survives betwwen 12-24hrs but whats the average time you girls ovulate all together? I have a Clear Blue Digital ovulation kit and it has given me one peak day (10th june) and everyday since then its given me a high reading... Surely i dont ovulate for 10 days??? Orrr... Could this be a surge thats come through since i havnt ovulated or mentruated in a year and a half up until a few months ago??
