What drugs should not be taken before the HCG and progesterone test?

Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Hello, Dr. Gao! Today you prescribed me 1 box of progesterone capsules (Yimaxin), 1 box of Diflucan tablets (Daphne), and 2 bottles of Jianshuan Fetal Combination. When I was 50 days pregnant (Friday, July 15), I had a blood test for HCG, progesterone, estradiol and ultrasound in the morning, and I was instructed not to take any medicine before the blood test. At that time, there were many people, so I didn’t pay much attention. Can I take it the day before? Also, what about progesterone and antifetals? Also, is it better to take these medications after meals? You have a lot of patients, you work very hard, take care of your health! Doctor: Progesterone capsules (Yimaxin) and Diflucan tablets (Daphne) are usually taken twice a day, and blood is drawn on Friday morning before taking the medication, otherwise it will affect the lab results and lead to the false impression of higher blood progesterone levels. After pregnancy, intestinal peristalsis generally slows down and stools are generally dry. If you have a dry stool, take it before meals, or after meals if it is very thin.
