Thick jelly-like CM - before or after ovulation?

Lizzie

I always have a big deposit of jelly-like cervical mucus every month, mid-cycle around ovulation time. It’s usually very clear and thick with no odour. It comes out all in one go, stays in one lump, and then my CM is very normal afterwards. Can anyone shed some light about whether this means I HAVE ovulated or I will ovulate SOON? Negative LH test but still a strong line.
