What are the side effects of excessive injection of progesterone?

Patient's question:

Lower abdomen feels heavy, slight bleeding after exertion

Doctor's answer:

Progesterone can promote the proliferation and secretion of the uterine mucosa. Long-term use of progesterone can cause liver damage and may lead to other complications, such as Cushing's syndrome. Additionally, there are some side effects, such as occasional rash, itching, breast enlargement, fatigue, nausea, etc.
Advice: Nausea, dizziness, headaches, fatigue, hives, and breast swelling may occasionally occur. Long-term continuous use may result in reduced menstrual flow or amenorrhea, abnormal liver function, edema, and weight gain. A slightly increased dose may not cause significant harm. If you are concerned, consult your doctor, who will provide a satisfactory answer.
