Cm confusion

Sedaya • My name is Sedaya and I'm 23. My husband and I have been together since 2009 and got married April 2015. We have a four year old daughter and had our second daughter 4-16-16 :)
This month has been confusing for me. A few days after my period I had major cm which never happens! Then before my fertile window I had ovulation like cramps and watery cm. I took opk the past two days and negative and I've been very dry. I really haven't produced any ewcm this month so far. I'm going to keep using opks but I'm so confused. Maybe I ovulated early. At this point in the month I usually have way more discharge. I don't know if anyone has had similar experiences.
