Hi,
Progesterone hormone is recreated from the cover of the ruptured follicle (corpus lutetium) & helps uterine lining thicker so that fertilized ovum can be easily implanted in it.
Hereafter, progesterone is created to help the maintenance &growth of
pregnancy.
Suggestion is a progesterone preparation &helps pregnancy as described above.
It is given to aid pregnancy when ovulation is normal ...&if progesterone may be lesser, pregnancy may not be saved.
In my view, progesterone supplement should be started approximately pn ovulation day.
It must be taken very regularly at a fixed time of day. Unprotected sex should be done 2 days before, on the day &two days after the ovulation (ovulation can be known by LHsurge test).
Please discuss this with your treating gynecologist, get your ideas cleared&follow the instructions given by the doctor.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Vasudha Jayant Athavale, General & Family Physician
