Patient's question:
I usually have a very regular menstrual cycle. In July, my period lasted more than 8 days, and I tested positive for weak HCG in my urine. When I had a 47-day period, I experienced light bleeding. I received 3 days of pregnancy preservation treatment, but at 50 days, I miscarried. Even at 50 days, my urine HCG test was still weakly positive. This time, my period lasted more than 7 days, and I had early pregnancy symptoms like nausea and vomiting, but the urine HCG test was negative. What should I do?Doctor's answer:
Hello: Luteal phase defect refers to insufficient progesterone secretion by the corpus luteum or premature luteal regression, leading to inadequate secretion of the endometrium and consequently difficulty in implantation of the zygote or early pregnancy miscarriage. Luteal phase defect may be related to insufficient secretion of LH and FSH by the pituitary gland, excessive or insufficient prolactin secretion by the pituitary gland; in some cases, it may be due to the immaturity of the zygote itself and its insensitivity to gonadotropins; in other cases, it may be related to insufficient ability of the corpus luteum to synthesize progesterone, or an imbalance in the ratio of estrogen and progesterone. It is recommended to visit a specialized hospital for further diagnosis to determine the condition and receive appropriate treatment.
