Ovulation (Day 21 Progesterone) Blood Test

Why would you benefit from an Ovulation- Progesterone blood test?
Progesterone is a hormone that helps to prepare your body for pregnancy. After
ovulation, your progesterone slowly rise, peaking around day 21. This is why the test
needs to be taken on day 21 of your menstrual cycle, as this is approximately when
progesterone levels are at their highest. Progesterone helps build up the lining of your uterus — where a fertilised egg can implant.
The empty follicle left behind becomes a corpus luteum — a completely normal cyst that forms on your ovary every month. This is what continues to produce Progesterone. If an embryo doesn’t implant, the secretion of progesterone from the corpus luteum will taper off over the next 14 days.
