What is going on?!?

So we start Clomid this upcoming month. Just waiting on AF and she usually arrives on day 30 but I am currently on day 38 🙁. I had a HSG test (no issues) at the start of July and then my progesterone tested on day 21. The odd thing is my levels were really low. It was clear I had not ovulated. I have had a faint tint of pink in my CM the past 2 days. I keep thinking AF is doing to arrive and nothing..... I took a test a few days ago and it was negative. Looking for advice.
