Did anyone have acne or skin changes ahead of their BFP?

I woke up on 4 DPO and my skin had seemingly changed overnight. I usually have very smooth skin - I rarely got pimples even as a teen - and now it seems like every pore on my face has turned into a bump. I've also got a few pimples - including one on my earlobe!!

I know this would be very early for implantation but I can't think of anything else that would change my skin so drastically in such a short period of time. I do sometimes get stress-related pimples but those would be one or two big ones. This is a different kind of skin change that seems to be the overall quality of my skin. I haven't changed my soap, shampoo, detergent or anything that would cause skin irritation.

AF isn't due until Jan. 3, 4 or 5 (my cycle ranges from 26-28 days) so I can't test yet. Instead, I'm obsessively researching acne before BFP! Would love to hear your experience.
