Not seeing your symptoms? No worries!
A condition caused by low levels of progesterone, the female hormone that controls menstruation. An imbalance in the level of progesterone affects normal egg release (ovulation) and can cause irregular periods. This is also seen as a possible risk factor in early miscarriage and difficulty getting pregnant. Known causes include anorexia, excessive exercise, obesity, diabetes or other hormonal problems (e.g. thyroid disorders).
Your doctor may ask these questions to check for this disease:
Treatment may not be necessary unless planning for pregnancy. Treatment depends on the cause, such as gaining weight in anorexia or losing weight in obesity, correcting other hormonal imbalances etc. Progesterone supplementation may be required in some cases to reduce risk of miscarriage and help with fertility. A specialist consultation is advised.

Q.
Embryo Not Implanting? The Medical Reality and Your Proven Next Steps
A.
Implantation often fails because of embryo chromosomal abnormalities, progesterone or timing issues, and uterine lining problems, with immune and metabolic conditions sometimes playing a role; even a normal looking embryo may not implant, and a euploid embryo implants only about 50 to 70 percent of the time. Next steps include reviewing embryo genetics and grading, optimizing progesterone and transfer timing, assessing the uterine cavity and lining, and checking thyroid, glucose, and vitamin D while addressing lifestyle factors; many more important details that can affect your personal plan, including when to add testing and urgent symptoms to watch for, are explained below.
