On the third day of the menstrual cycle, if the flow is very light, does checking the six sex hormones affect it?

Patient's question:

No

Doctor's answer:

Hello, it won't affect you. The possibility of reduced menstrual flow is due to factors such as the condition of the endometrium itself, low estrogen levels, or gynecological inflammation. Additionally, having blood tests for the six sex hormones on the third day of your menstrual period will not be affected. You don't need to worry too much. It is recommended that you do not take hormone medications before the test and avoid drinking water the night before.
