When checking the six sex hormones for a missed miscarriage, in which month is it most accurate?

Patient's question:

No

Doctor's answer:

If the check is performed on the 10th day of the menstrual cycle, it is difficult to determine whether it is the follicular phase or the ovulation phase. If this person has a short menstrual cycle, only 24 or 24 days, her 10th day of the menstrual cycle is the ovulation phase; if her menstrual cycle is 30 days, then it is not the ovulation phase. Obviously, the check result on the 10th day of the menstrual cycle cannot accurately determine whether the endocrine test result is normal.
