What on earth is going on with my ewcm?? Am I ovulating early?

Right started charting this cycle, not just opks and also started epo (for ewcm) and a b100 complex (for luteal phase defect). Anyway, normally get LH surge day 16 and about 5 days of ewcm. Yesterday had no cervical mucus externally, this morning = sticky cm, afternoon = creamy, this evening ewcm! It's only day 9 of my cycle! What is going on? Before you say 'just go bd' we're using a donor so I need to tell him.
