Audiogram An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels and the X axis represents frequency measured in hertz. The threshold of hearing is plotted relative to a standardised curve that represents 'normal' hearing, in dB(HL).
Test every 12 hours not every 24 hours. The perfect time for sexual intercourse is within 12-24 hours prior to the ovulation predictor FIRST turning positive. Especially if you test only once a day. This may sound like a surprise, but making love only after first getting a positive OPK may not get you pregnant at all.
Share. I'm on cycle day 15 and started spotting on cycle day 12, then it stopped and then more spotting on cycle day 14, and darker pink spotting on cycle day 15. This is 2 weeks from my last period. I had a positive OPK on cycle day 12.hare. I'm on cycle day 15 and started spotting on cycle day 12, then it stopped and then more spotting on cycle day 14, and darker pink spotting on cycle day 15.
