Yes: Yes, the surge in hormones can be masked by hydration.

Yes: It depends on whether you might have missed your ovulation time. Many patients can either ovulate earlier or later than might be expected. A Progesterone level approximately 7 days after your clinical findings of ovulation can assess whether you had truly ovulated.

Yes: Ovulation predictor kits detect luteininzing hormone (lh) that accompanies the release of an egg but are inaccurate in some women. Basal body temperature (bbt), pain (mittelschmerz) and cervical mucous may also represent ovulation but vary widely. Ultrasound or electronic aids (clearblue easy, ovwatch or ovcue) are also available. However, only pregnancy is an absolute indicator of ovulation.
