I need an advice, can anyone help me out

Sree

I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> last Friday 7th October , Last tuesday/Wednesday I got sticky CM which comes after you ovulate. 

I never normally ever get Watery discharge but had some the other day & loads today! I'm 12dpiui 

Is this a symptom? Or could it be AF is on the way? I don't want to read to much into it but thought I would ask.
