EWCM / Ovulation Timing

In the past I have always had a large amount of EWCM - particularly a big blob of it that would come out all at once.

Last month, which was my first proper month TTC I didn't notice that I had that which is unusual for me.

I have just had a positive opk and haven't noticed the large blob of EWCM again yet. There was a small amount yesterday but that's it.

Does a positive opk and EWCM usually happen at the same time?

If I don't get the big blob that I usually get does that mean I'm not ovulating properly?

Just curious about timing as I've never used a opk before.

I'm BD'ing every night so should catch the right time anyway!!!
