Clomid confused?

I’m hoping someone has an experience to share like mine because I’m very confused.

I took Clomid (5-9) and bd 5 times during fertile window. About 3-4 days ago, I noticed spotting which I’m assuming was implantation bleeding. It was brown and sticky. Then yesterday I had more after a day or two without having anything. Took a frer this morning with fmu and had a vvvvvfl.

So I’m confused on why I keep having brown spotting. I get upset bc i keep thinking it’s af.

Thank you all so much!
