Itchy around ovulation

So I've already had my annual checkup and I'm clear but a couple days before my ovulation I itch down there. It's not like a persistent itch or anything, it's just like your head itches so you scratch it. It happens through out the day and I only notice it before my ovulation. Theres no other symptoms, no burning, no swelling nothing only a itch every once in a while. Anyone else have this?
