am I ovulating?
If you have irregular periods or are taking a long time to conceive then it is possible that you are not ovulating every month
Ovulation creates a rise in progesterone which can be measured by
a blood test
a rise in body temperature
Ovulation predictor tests can be useful to help you know when ovulation is coming but a positive test doesn’t mean that you are ovulating - only that your body is preparing to.
day 21 progesterone test for ovulation
this blood test is done roughly a week after ovulation (so on day 21 if your cycle is usually 28 days)
your GP can order this for you
it is ideal to be tested 3 months in a row as many women occasionally miss ovulating
results above 20 suggest a probable ovulation though it may be weak
results above 30 confirm ovulation
temperature charting for fertility
When the egg is released from the follicle at ovulation the empty follicle that remains begins to produce progesterone.
Progesterone makes your temperature rise - it shows us when ovulation has taken place and whether ovulation is strong enough.
The idea is to take the temperature at its lowest point each day, this the basal body temperature also known as BBT.
You need to have been asleep for at least 4 hours for the temperature to drop to its lowest level.
Take your temperature when you wake up before you do anything else. The temperature naturally rises when we are active so you need to take it first thing. If your sleep is disturbed for any reason, or if you wake at a different time than usual, then just make a note of it on the chart so we know to interpret that days result accordingly.
Record the temperatures on a graph so you can see what pattern they make. You are looking for is called a biphasic pattern - this simply means that temperatures are higher in the last 2 weeks of the cycle before the period comes.
You can download basal body temperature charts from www.fertilityfriend.com and there are also a number of apps available for your phone.
Other information such as LH ovulation predictor test results, and cervical mucous changes can be added to the chart.
Cervical mucous increases and becomes clear and stretchy like egg white when oestrogen levels are high indicating that ovulation will occur in the next few days.
