Spotting in LP and TTC?

My cycles consistently have an LP of 12 days, 13 max. However I also always start spotting day 10-11 before my period. Very light and definitely not the start of a period yet. I assume this is my progesterone dropping.

Do you think essentially a 9-10 day LP (before spotting) is a worry for TTC? Any similar experiences? Thoughts on chatting with OB about progesterone?

Probably overthinking 🙈
