Help! On Cyclogest, 9dpo, big temp drop and spotting

[Peach Blossom]

Hi, hoping someone can help me out. Am on cyclogest and have been for 4 days. I am 9dpo and my temp dropped by 0.3 this morning and I've had spotting for 2 days (discoloured cm, not red). This is the first time I've take progesterone, but surely I shouldn't be spotting or having huge temp drops whilst on it? Any advice? Not on any other form os assistance.

PB don't have a clue but didn't want to R&R.

Hopefully, it's what I think it is
