So confused

Hi! So I’m so confused. Last month was my first month post IUD and it was the longest cycle I have ever had- 32 days. This month, I feel right on track, my period was a normal length I’m on CD12 and my 4th day of high on clearblue advanced, but my cheap strips are hardly showing lines! We are on vacation and have spent a lot of time outside and I’ve been drinking tons of water, so could it be I am just too hydrated? I’m starting to get frustrated because I usually show some type of progression. Also, tmi, but I have EWCM that started today. I usually always ovulate on CD14. Anyone else have super super faint lines on OPKs then a bright positive? Thanks! Pic below is from 1:30 this afternoon.

EDIT: the second pic is a 2 hr hold with no liquid. It’s darker. So maybe it is because they are diluted?
