Cycle all messed up after miscarriage

Laura

To be brief...

Miscarried naturally at almost 10 weeks (missed miscarriage GA 6 weeks 4 days) from Nov 30th- Dec 3rd then spotting until don't know when

Got super positive opks around 17th Dec but no EWCM

Had a very light first period - spotting and 2 days of light flow red blood 30th -31st Jan

Today loads of EWCM but nowhere near positive opk and it's cloudy.

Is ovulation near? Shall I BD in case? Why was my period so light I was expecting a "bad" first one?

My cycles were very regular and symptoms of ovulation/period coming were easy to read and now I'm just confused!
