Progesterone – does your cycle have what it takes?
We thought we’d get back to some basic stuff this week and talk about your menstrual cycle and the part progesterone plays in it.
If you’re having difficulty in conceiving or are dealing with miscarriage, you’ll probably be advised to have a progesterone level test to check your ovulation. You’ll also probably be told that you should have it on day 21 of your cycle. But… is your cycle 28 days long? If not, then having a test then won’t yield an accurate result.
You need to have the test seven days before your period - so work out which day is the one for you, and book it then.
Progesterone is important in the second half (or luteal phase) of your cycle. It prepares the lining of the uterus for holding a fertilised egg, and women who have low progesterone may not be able to carry a successful pregnancy. If you’ve heard the term ‘luteal phase defect’, this is what it means.
For women, the interaction of fertility hormones is very complex, but as long as you know your own cycle, you’ll be well placed to get the most accurate results from your tests.
