Confused with clomid

So I don’t ovulate on my own. But I did on my 3rd cycle of Clomid.

My period started Feb14.🩸

Clomid day 5-9 Feb18-22💊

OPK day 14-15 Feb 27-28📈

March 5 bloodwork OVULATED‼️

Expected period date March 14

Was told if I don’t start by March 14-15 take progesterone 400mg to help start period.

Tested NEGATIVE both March14-15 ➖

But I thought since I ovulated I would get my period on my own???

I’m so lost on this🤷🏻‍♀️
