EWCM at 5dpo?

Sara

So I sometimes notice some ewcm about cd9-10 starting and I o cd12-13. I’m 5dpo and noticed the past few days I’m having some more now after o. This afternoon cd18 I wiped and had a small stretchy blob on tissue. Why would it still be around after o? I definitely O already and had used preseed for the first time this cycle but it’s been a few days since.
