After stressing so much about it fri I discovered that some labs test it in different measurements there's
nmol/l = nanomoles per litre
ng/l = nanograms per litre
The normal in woman Progesterone levels tend to be < 2 ng/ml prior to ovulation, and > 5 ng/ml after ovulation. Anything over 5 (but best to be in between 10 and 20 means ovulation has occurred.
As for nmol/l this is what I found :
1. Progesterone > 30nmol/l – ovulation has occurred and the corpus luteum is producing sufficient progesterone to induce adequate secretory changes in the endometrium to assist implantation.
2. Progesterone 3-30 nmol/l – ovulation has occurred > 10 days ago or < 5 days ago, or if ovulation did occurr 5-10 days ago, the level is probably not adequate to sustain endometrial growth for satisfactory implantation.
3. Progesterone >120 nmol/l – two or more follicles have been recruited
4. Progesterone < 3nmol/l – no ovulation in previous 14 days.
Phew! I was rubbish at biology at school but slowly getting better haha!
