Should I test again... or am I out this month?

Ch

So I’m officially a day late for AF. My cycle has been exactly 30 days for the last 10 cycles. I took a FRER and got a BFN at what I think was 12dpo. (Maybe 11dpo) I had ovulation symptoms on the 9th and 10th of July but I normally get a sharp pain during ovulation and I felt it on the 9th. Which is why I think I ovulated then. I used first morning urine when I tested at 12dpo but I drank a lot of water the day before (about 12 500ml bottles) and I think (am hoping) that my obsessive water consumption may have skewed the results. Also the last time we bd’ed during my window was the 8th as my SO works out of town. So even if I ovulated late it would have to be within a few days of the 8th because the sperm wouldn’t last longer than 5 days at max... am I out this month or too soon to tell?
