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.
Anonymous. 1  They only do D3 and D12 ultrasound and blood work, ovidrel on D12, iui on D14. I have had positive OPk results since D12 evening (2hours after the ovidrel shot), but I also heard that ovidrel may affect OPk results, so I can't tell if I ovulate based on the OPk results.
