I have had a hard time capturing a peak this cycle, all daily and then double daily tests around presumed fertile window have been negative. No EWCM this cycle, very small amount, once when wiping, but negative OPK - very very faint at that time. Watery ++ consistency in the past 36 hours but was negative during this time also - very faint barely visible with concentrated urine.

Then.. this sudden potential peak this evening. I have been exceptionally hungry and headaches as the only potential symptoms. Not pregnant, all negative including at the time I took this OPK. Im cycle day 26. I believe my covid booster shot may have extended my cycle this month?

My urine was very concentrated this evening could this be a false positive or is that not possible?

Any thoughts would be greatly appreciated ❤️
