Positive OPK 5DPO?

[jem77]

Sunday the 15th I had lots of EWCM and a positive OPK. I swear I felt O on Monday the 16th and had 2 negative OPK's. So, today (what I think is 5DPO) I had LOTS of EWCM so I took another OPK it was positive! Please help!!
I have felt crampy and tired all week and my bbs are swollen... normal for after O....
