Period no show?

Cycle day 42 - 7 days late, negative tests.

Around ovulation I had some mild pain and bloody spots in my EWCM. EWCM has continued from predicted ovulation to present.. no PMS symptoms - I usually get the whole lot, bloating, cramping, mood swings, hunger, tiredness and sore swollen boobs for up to a week before my period starts.

Any advice/ ideas on my why period is late?

Only time I’ve had a late period was when I had an ovarian cyst (I don’t have PCOS) last year but this was accompanied with pain and resulted in exploratory laparoscopic surgery due to rupture of the cyst and suspected appendicitis.
