Are dating scans in pregnancy accurate
If you tracked these changes, the day before your mucus changed to a thick, tacky, cloudy, dried-up mucus was the day of ovulation, and your likely date of conception.The day of ovulation, your mucus would have been at its most thin and watery, as well as clear and stretchy like egg white. Once your doctor or midwife gives you your due date, count 38 weeks back on a calendar to find your most likely conception date.That one to two day window after your surge is the likely time you conceived.If you kept a basal body temperature chart (BBT) during the cycle you conceived, this is a useful tool to help pinpoint when you ovulated and therefore conceived.The day of your definitive positive reading is the day of the biggest increase in your LH.
It is important to remember the lifespan of the egg and sperm can influence the date of conception.
An ovulation predictor kit (OPK or LH kit) reliably predicts the window of ovulation, according to a study published in 2000 in Human Reproduction.
